4M Q7 / B9 RS5 6 Piston + 380mm SQ5 Rotor.

[peterpark0]

I think I'm the first in the states to do this. I seen this combo somewhere out on drive2.ru but no but there was no information. So with a bunch of research everything "should" work with a 12mm-ish spacer. This is just about accurate, but I would suggest using a 14-15mm spacer instead.

Special shout out to UkuRiSh, H4mm3R2, UltraSchnell34 for contributing and being crazy enough to attempt this too!
H4mm3R2 - Some crazy genius! Russian dude I think? He was the first ones to talk about the B9 S4/S5 caliper with the 356x34mm rotor. And does work with the massive 400mm SQ7 caliper too!
UkuRiSh - Created his own bracket to use the factory 4M Q7 / B9 RS5 375x36mm rotor.
UltraSchnell34 - Using the MB 375x36mm rotor. (Very affordable and accessible rotor!)

Procedure

This is the exact same concept of the B9 S4/S5 Caliper + 356mm C7 A6/A7 setup. There's lots of useful information on this thread, so read this first before asking questions. (All the real good information is on the last few pages!)

No mess brake line change & Bleeding
- Hold down the brake pedal. (Have someone or place an object(Snow brush) to push the brake pedal)
- Pop open the bleeder valve and suck out some of the fluid with your brake bleeder tool of choice. Or just let it drip out.
- Disconnect the top line and there should be little or no fluid that comes out.
- Do for both sides obliviously!
- Release the brake pedal.
- Bleed your brakes.
- Start the engine and pump the brake pedal a few times, This allows the brake pistons to fill up and move. Turn off engine.
- CHECK FOR LEAKS!
- Tap the caliper and bleed the brakes again.
- Pump your brakes before driving and bed in your brakes. Rebleed if needed.

I like to use the Capri Tools Vacuum Brake Bleeder, it's super simple and easy to use.

Btw, I used the 4M Q7 line and it's a direct fit!

M12x1.25 95mm bolt
I used 100mm bolt. You can use washers or cut down the bolt down to 95mm.
If the bolts are too long it will interfere with the knuckle.
I have a bunch of these bolts (Uncut, 100mm) and custom aluminum washers for sale, Contact me!

Everyone complains about a mushy/delayed brake feel. I don't have that issue with this. It feels the same as the stock S5 brakes, there may be a slight change in pedal fee where you have to push the pedal in harder, l but I think that's in my head. The car stops hard on factory pads!
Brake bias is fine. On my BMW BBK, you could really feel the nose-dive from the front end. On the s5 it stays planted front and rear, unless you really really hard stop.

There shouldn't be a problem with B8 brake lines fittings going into the Akebono calipers. The fittings thread should be the same.

Look at this guy with the 350mm Akebono with B8 SS line. But I think the B8 RS5 SS line would be better, plus the RS5 is threaded/twist-able on the caliper end.

I may have a lead on a Stoptech set that i test fitted today with the 90 degree like the RS5. I'm pretty sure it the same length as well.

I'll try and post some pictures and part numbers tomorrow before i leave town.


Did you end up getting them powder coated? I'm trying to find a piston rebuild kit since the dealer wants a crazy amount.

I didn't want to disassemble the caliper, with a chance of damaging the seal. Since my calipers were new-ish. So I just ended up painting it with VHT Gloss black engine enamel and clear coat.
I'll do a powder coat and replace the seals in another 20k miles.

Pics

Grinded down the casting marks and sanded down the whole caliper wtih 60 grit. Orange cleaner/degreaser + Dawn dish soap bath to clean.

I'm having Oleg make me a set of his brackets so I can use the 375x36mm rotors as they will fit under a few 18" wheels.

I test fitted with my existing 380x36mm setup off the SQ5 a few months ago.

https://i.imgur.com/4EP4IHj.jpg

From what I could tell you would need to grind down the bracket a bit to have it all bolt up cleanly.

Nice nice, Is that the non-aluminum version of the rotor? & I want a copy of his bracket too! Those 375mm loooks so much better!

And yes there was some grinding involved, Just like the B9 S4/5 setup.

Finished up and getting clean

So after testing fitting this setup originally with Mercedes GL550 Rotors I learned that unfortunately the rotor bore is 1mm smaller that the S4 hub and that the hat is 2mm too short which unfortunately causes contact with the inner edge(where the pads mount) of the caliper...[headbang] because of this i went with the SQ5 rotor which fit perfectly! I also test fit a new Q7 Rotor which had a similar problem with the hat being to short.

So after having these bad boys on for a couple weeks I've gotta say they feel great!

List of parts used:
Audi 4M Q7 front calipers and brake pads
B8.5 SQ5 front rotors 380mm
Hareward kit purchased from Peterpark0
RS4 Stoptech SS brake lines
B8.5 front brake pad sensor

Thank you Peterpark0 for putting a lot of this together and for the hardware kit! It worked great!

So the 19" Peelers fit! These brakes actually look better on these wheels vs the RS5 20" rotors.

& The color really makes these calipers pop! HOLY SHIT that looks good!

So now do you have a bunch of spare rotors laying around? lol.

[UltraSchnell34]

He he he kinda.... well thankfully i work at a shop and was able to return and test fit a lot of stuff without paying for it... lol but yea i have my set of spacers and bolts from trying the run the MB rotors.

I like the yellow but i'm honestly really disappointed in the VHT Yellow caliper paint. I cleaned, prep, and primered the calipers and they started chipping before i ever got them installed. I'm not sure how many times i had to repaint these [facepalm]
Anyway i may repaint them before this big event we have going on in 3 weeks, it will just depend on how good or bad they look the week of.

Side note while ordering new wheels i had to look into a brake template to make sure of clearance and they are very very similar to the Stoptech ST-60 kit template. I'll verify the clearance with the new wheels but i had a few sets to test fit(Vorsteiner and BBS) and didn't have any issues.

[UltraSchnell34]

Here is the clearance from the inside of the wheel. I also made a rookie mistake and didn't put in the top pad spreader clips the first night... which is why the back looks like shit(part of the other reason i'm thinking about repainting them)

You can find them pretty cheap off Ebay if you wanted to piece together a kit.

I'm hoping to swap down to the 375x36mm rotors and run a set of 18" wheels.

I still need to test fit my winter wheels. I am like 60% certain they will fit...

[UltraSchnell34]

My new wheels should be here next week. When I swap over I'll see if we have any 18s I can use for testing.

I've looked everywhere but I can't find a set of 375 rotors that will still fit without a lot of modifications.

[whiped]

Vosh shared that you can use the CTS-V 375x36mm rotors and just redrill them to 5x112.

I'll be using the Q7/RS5 rotors with a bracket to adjust for the hat offset.

[UltraSchnell34]

Another option that just remembered is that all the new BMWs are switching to 5x112 bolt pattern but i havent done much research into there hat and rotor sizes.

If you look at the F80 M3/4. The factory 18in(513m) cleared the 380mm brembos due to the barrel design.

On my 335, I had 370mm brembos and it cleared that same wheel (513m) but my factory 18's didn't.

So good luck! It's just trail and error at this point!

No worries man, it would have been a tight timeframe regardless.

Designs are done, just waiting for them to be CNC'ed. If you want more details you can ask Oleg directly.

13lbs Calipers with pads"

Depending on the wheels I'm sure, but i did test fit a set of 18's just now and they would fit however the set i had at the shop was from a B7 S4 so the hub wasn't the same but it did clear the barrel [up]

Yes, the 375mm rotor is the standard for the caliper but you can run a 380mm which is also a cheaper option.

So basically the voshmods rear setup. Would be nice if you could create the bracket to work with the offset of the R8 rotor. So you could have a 2 piece option that didn't break the bank. I would be surprised if you could get it to work though. The R8 rotor is roughly 7MM taller than the S5 rotor. So it would sit over 1/4" further back on the hub, which is likely we why we have never seen a kit for this.

Just noticed you said the Q7 caliper, that rotor is a 330x28, the R8 is a 356x32. You would need the R8 caliper to run those rotors, too thick for the Q7 Brembo.

Waiting time is stupid long it's not me ! Issam is doing CNC work and it's not my fold then way it's takes so long.

My goal is kept cheap as passable because after track day I have to change all brakes front and rear ! Audi A8,S6,S7,S8 rear rotors cost so cheap I can replace after every visit of the track days , Front one little more expensive but still light weight and cheap 375mm Q7/RS5

When I was posting my rear setup I had my Tesla parking calipers in my garage this is even before I saw your setup that’s why I comment in your FB post “ is this Tesla electric caliper” because I know exactly what was it. First design I did OEM calipers for people who can’t spend more money on Tesla caliper or they would like to kept OEM for some reason. When I finished design with OEM calipers I start work on Tesla parking calipers design because those calipers is slim and they looks a lot better and sporty ! it’s noting to do with you lol ... Don’t act like you the best engineer in the world ! You not only the person in the world with ideas, are you sure your welded nut is strong enough to handle heavy loads on the track days ? My design is created to handle heat and heavy force on caliper bracket that’s why is one solid metal piece ! When I finished my rear setup I designed front 6 pot RS5 / Q7 to clear 18” wheels with biggest brake rotors passable! that was 375mm and now you telling me I stole your idea pshh... This is my last comment in here !

[voshmag]

That sure was a defensive/offensive response

Find it odd that you spent all that time making the OE Caliper kit because people might not want to spend an extra 125 on the tesla calipers then start working on your tesla design after mine was on the market.

However in the world of invention if you have a good idea chances are somebody else in the world is working on it as well.

As for acting like I'm the best engineer in the world, well I know darn well I am not. Dont confuse my displeasure as being cocky with my abilities. I'm bothered with the dialog we shared "I am using the oe caliper and if it does not work out I will most likely go with your kit"... Then releases a strikingly similar kit 10 months later.

As for you comments reguarding the itegraty of my kit.
1) over 100 kits on the road with zero issues, the first installed kit was 1.5 years ago
2)yes the welds are strong enough
3) even if the welds on the nut failed the kit would remain functional... The welds are not needed but simply fault tolerance
4) all my kits avoid a single point of failure (excluding brake lines because there is no way around this)
5) the caliper will fail long before my bracket does... Its overkill.

Dude this awesome. I’m looking to upgrade my A4 B8.5 with RS4 B9 calipers and 375x36 rotors. Do you know anyone to get these alloy cnc’d adapters?

[Waffles_s4]

To voshmag and UkuRiSh: if u want to protect a design, or idea, you trademark it. Otherwise, you are wasting your time arguing.

Show me ONE single car manufacturer which re-invents on their own every design and idea out there in the market?

You always see car makers coming up with their own ideas, only to be used by others in the short-term. Sometimes they are the same, other times better (more refined), or even worse. Engineers often take a car, strip it to the bolt, and learn from others. Then they improve things, and so on. The opposite is true.

If every car maker re-invents every single option, design or theory, you will spend 10 times more than what you ar paying today.

Test fitting some wheel options
128194

Finished up and getting clean
128196

So after testing fitting this setup originally with Mercedes GL550 Rotors I learned that unfortunately the rotor bore is 1mm smaller that the S4 hub and that the hat is 2mm too short which unfortunately causes contact with the inner edge(where the pads mount) of the caliper...[headbang] because of this i went with the SQ5 rotor which fit perfectly! I also test fit a new Q7 Rotor which had a similar problem with the hat being to short.

So after having these bad boys on for a couple weeks I've gotta say they feel great!

List of parts used:
Audi 4M Q7 front calipers and brake pads
B8.5 SQ5 front rotors 380mm
Hareward kit purchased from Peterpark0
RS4 Stoptech SS brake lines
B8.5 front brake pad sensor

Finally got all the parts so i could do a real test.

The MB rotor is $100 each instead of for example sq5 380 disc for over $300

Q7 caliper
MB 375x36 rotor (zimmerman 400.3684.20) You need to drill the centrebore 1mm
Brembo pads (P 85 165)
8mm spacer for the caliper bracket.
3mm wheelspacer behind the rotor to get it out.

That 3 mm spacer behind the rotor scares me! Overall that looks really good!

Also thank you for finding the replacement brake pad! The only options at the time were the factory Q7 pads along with the factory RS5 soft pads.

So you did you make your own spaces or did you get one from peterparker0 or Savrog? How much grinding on the caliper did you have to do?

Did you get the Brembo pads because you didn't want the factory Q7 pads or because of some of the clearance issues others have expressed with the smaller 375mm rotor?

I am going to be doing this in the next few weeks so I want to start getting all the stuff around now.

First question: Check out post #11 in this thread to see how much grinding you have to do. If you need spacer I'm one of us either have an extra set (depending on what size rotor) or can have them made and shipped out if need.

Second question: Speaking from personal experience I didn't have any issue running the OE Q7 pads on the 375mm when i test fitted. Also there shouldn't be any issues running the OE pads because the factory rotor for the Q7 is a 375mm.

I strongly recommend these brakes its a big upgrade they look great and I get people coming up saying "Holy Sh!t those brakes are huge" also throw on some Porsche Macan brake ducts and call it good.

Thought i update this.

When i did the final install i realized that the disc was not i center of the hub. Because it was spacered out it did sit on the wheel hub which is smaler then the disc hub. I tried that way anyway and got vibrations at around ~120km/h.
So i got some hubrings for the rotor but it had a small gap anyway so it was not really centerd but the vibrations pretty much was gone.
I had a pair extra caliper brackets laying around so i had them remove 2mm on them so i wouldent need the spacer behind the rotor and just installed everything and its good!

Thing is that i thought about this before i did the test fitting but becuase i had the spacers laying around i went that route and kind of forgot about machine the bracket.

So for this setup with the MB rotor you need to:

Machine the centerbore 1mm.
Machine of 2mm of the bracket.
Make a new hole in the rotor for the screw that holds it in place.
10mm spacer for the caliper and bracket. (i said 8mm before but since the rotor was not in centre i ofcoure got the wrong number.)

Endy1, when you say you machined 2mm off the bracket, do you mean off the mounting point of the bracket to the hub? You took it down 2mm to bring the rotor inboard, is that correct? Do you have a pic you could show of the area you machined 2mm from? Thanks!

2mm here will make the caliper come closer to the car.

Question about this setup. I have a 2011 Q5 2.0 TFSI Quattro. I think steering knuckle identical to B8 A4 & S4. I am deciding between the Q5/Macan 4 piston calipers which supposedly bolt right to the steering knuckle without brackets, and this larger 6 piston setup. Just to confirm, these Q7 4M calipers have a bracket which attaches to the steering knuckle? And no machining is required if using SQ5 rotors? I will be running 20" wheels so clearance should not be a problem. Thanks and sorry for the semi-hijacking of the thread.

If you use the 4M calipers at all you will have to grind and use spacers unless you get a custom bracket.

genuineaudiparts.com has the right listed for $230.11 and the left for $424.56. The cost isn't that terrible through them, but I'm just confused as to why there's such a price discrepancy between the sides, its not like the drivers side caliper has electronics or something in them, they're visually the same.

Maybe it’s a supply thing, the used ones are selling for more than that in some cases! Everything has gone up by almost 25% the aluminum for the brackets I made, the bolts, and the machine shop all have drastically changed. Thanks for the information though.

Honestly I have put my hands on several sets of these and I have only seen a slight non functional difference in one. I know the Q8 has painted versions of this same caliper. The letters may be production run trackers, but that’s a guess.

[B18b1ex]

Are the bracket kits still running around $400-$450?

Mine were always $450 shipped, I unfortunately have had to deal with an increase of about 25-30% in materials costs, machining costs and even shipping costs. I did not want to not use the 7075 so to offset that, I feel that $490 shipped is reasonable to at least offset some of the changes. I have invested in another run due to request and was upfront about the slight change. I also feel the use of this caliper along with the fitment of such a large variety of wheels with out spacers and the oem plus nature still makes this one of the best options for a large number of out platforms.

I fully understand, I wanted to get the magma interior for years finally just decided I wasn’t waiting anymore because a seat finally was close enough so I didn’t have to ship.

The other costs will depend on which rotors you want and where to get them. They range from $230 each for Q7, to $450+ for the Rs5 and $750 for girodisc. As for calipers we can now get Q8 or rs5 ones already red or Q7 and paint or Powdercoat. I have a set of Q7’s and S6 rears that if you would like to not have to source maybe we can work a whole package minus rotors. Because shipping those twice makes zero sense. Either way you have all the information. Best wishes

Yeah they're just weights to help prevent brake squeal, you talking about the C7 RS7/S6 6 pots that look similar to the B9 RS5's with the weight on the top? Those are Brembo's and these B9's are Akebono, must've been designed without a need for them.

Yeah, that’s what I’m referring to. It’s removable and seems to be one of the few differences I can spot between the calipers, but the Q7 version does not have a threaded hole for this weight, so it’s possible there are other differences. My thoughts however, are that these 6 pot calipers are the same across models and the only variables are the brackets and the rotor sizes; similar to that of the Porsche 6 pot calipers that are on the Panamera, Macan, Cayenne etc and are compatible with the Macan knuckle swap some members have completed on their B8/8.5s.

My thoughts however, are that these 6 pot calipers are the same across models and the only variables are the brackets and the rotor sizes; similar to that of the Porsche 6 pot calipers that are on the Panamera, Macan, Cayenne etc and are compatible with the Macan knuckle swap some members have completed on their B8/8.5s.


EDIT: found my answer in post #s 145-149 in the thread below; they aren’t the same.

Are you guys talking about caliper sizes?

There are three diffrent sizes.

400mm rotor
380mm rotor
350mm? rotor

Ive had calipers from Sq5 and Q7 in my hand and they are didentical except the size. And from what ive seen on the car the SQ7 looks the same, only seen the front tho.

I was referring to the size of the calipers and the size of the rotor they can accommodate. From my understanding, the B9 S4/S5 350mm calipers are different than the Q7/RS5 calipers for the 375mm rotors or SQ5 calipers for the 380mm rotors. I could be incorrect, but the information I’ve found thus far suggest this.

My goal is to run the 375mm rotors with the Q7 calipers and @B18b1ex ‘s bracket, but came across an inexpensive B9 S5 caliper today that needs a refinish and was hoping to make it work being that it’s about half the cost of an unfinished Q7 caliper.

I’m not sure it will work, while the pads may be interchangeable the 4M/q7/8 are bigger and may sit on the larger rotors differently. You could give it a shot and if it doesn’t work just sell if the price is that good.

I understand and can appreciate that. I enjoy the process of finding parts for my build even if it takes me some time. I also plan to use this project as a way to find a local powder coater while I decide what color I want the calipers to be. After selling my unused Macan setup and now planning for all four corners to be disassembled in the spring for coilovers, sways, UCAs & LCAs…I’d like to get what I really want out of the kit. I should really just start with your brackets in the next couple of weeks and then slowly build over the long winter, but that caliper at $130 caught my eye.

The SQ5 is for the 350mm rotor. Thats what i bought first and realized they dident fit my 375mm MB rotors. So they were nice so i could change them out for a set from Q7.

I think I'm the first in the states to do this. I seen this combo somewhere out on drive2.ru but no but there was no information. So with a bunch of research everything "should" work with a 12mm-ish spacer. This is just about accurate, but I would suggest using a 14-15mm spacer instead.

Special shout out to UkuRiSh, H4mm3R2, UltraSchnell34 for contributing and being crazy enough to attempt this too!
H4mm3R2 - Some crazy genius! Russian dude I think? He was the first ones to talk about the B9 S4/S5 caliper with the 356x34mm rotor. And does work with the massive 400mm SQ7 caliper too!
UkuRiSh - Created his own bracket to use the factory 4M Q7 / B9 RS5 375x36mm rotor.
UltraSchnell34 - Using the MB 375x36mm rotor. (Very affordable and accessible rotor!)

Procedure

This is the exact same concept of the B9 S4/S5 Caliper + 356mm C7 A6/A7 setup. There's lots of useful information on this thread, so read this first before asking questions. (All the real good information is on the last few pages!)
https://www.audizine.com/forum/showthread.php/758809-B9-S4-front-brake-caliper-specs-amp-availability-for-use-on-B8-s

No mess brake line change & Bleeding
- Hold down the brake pedal. (Have someone or place an object(Snow brush) to push the brake pedal)
- Pop open the bleeder valve and suck out some of the fluid with your brake bleeder tool of choice. Or just let it drip out.
- Disconnect the top line and there should be little or no fluid that comes out.
- Do for both sides obliviously!
- Release the brake pedal.
- Bleed your brakes.
- Start the engine and pump the brake pedal a few times, This allows the brake pistons to fill up and move. Turn off engine.
- CHECK FOR LEAKS!
- Tap the caliper and bleed the brakes again.
- Pump your brakes before driving and bed in your brakes. Rebleed if needed.

I like to use the Capri Tools Vacuum Brake Bleeder, it's super simple and easy to use.
https://www.amazon.com/Capri-Tools-Vacuum-Brake-Bleeder/dp/B00OM751EC/

Btw, I used the 4M Q7 line and it's a direct fit!

Everyone complains about a mushy/delayed brake feel. I don't have that issue with this. It feels the same as the stock S5 brakes, there may be a slight change in pedal fee where you have to push the pedal in harder, l but I think that's in my head. The car stops hard on factory pads!
Brake bias is fine. On my BMW BBK, you could really feel the nose-dive from the front end. On the s5 it stays planted front and rear, unless you really really hard stop.

Where can I buy the kit from you to make this work on my b8 s5. I already have the 4m calipers. Please let me know asap!!

There is no kit to do this, there’s a list of items and suggestions on what parts to grind.

Oleg and I to my knowledge are the only people offering a bolt on option and uses the 375mm rotor.

Nice! Yea these cars look really good with 356s in the rear! We initially did this bracket to run our S6 rear lightweight rotors on our B8 RS5 since we went up to 380mm lightweights in the front. RS5 guys typically aren't into sourcing used parts for stuff like this, at least not yet.

[bakedziti]

I don't have pricing yet. Not everyone wants to find and use used calipers. Just another option for people.

Interesting. Outside of having to bleed the system, I personally can't find much of a reasoning to go with that option unless the pricing is around $100 or less. These are just my opinions obviously, but a new or even used caliper and carrier allows you time for refinishing without down time while still being plug and play.

I asked my original question because I saw the JHM account get involved in the 356 rear dual caliper bracket discussion over on the B5 side and the market gap is present here as well with the vendor flop down in TX.

We've been making caliper brackets for over a decade so we definitely could machine something to fill the void. Just need to know exactly what it is people are looking for and how much interest there is. Also the possibility of black labeling for someone who wants to offer it themselves.

I just picked up my 356 rear calipers and brackets for $75 each and they're coming loaded with pads (I won't use). I recently picked up a set of Q7 6 pistons and paid $360 all in with 28k miles. Pretty excited about the setup but I have been picky in picking up my parts to keep costs down. My front brackets are going to be the most expensive part for me in this project at $450.

If anyone is interested, I can find rebuild kits for the akebono calipers too.

[SwankPeRFection]

What’s the exact part numbers for the rear calipers? Also, if someone chooses to just do the carriers, is that really the only difference between complete caliper/carrier assembly or the caliper truly is a bit bigger too? This is all in reference to a B8 S4.

Only the carriers are slightly different, only the dealer sells the carrier so often cheaper to buy the whole thing, plus you can powdercoat with less downtime.

The shields come off easily, I did not run the s6 shield. As for the calipers, I first did the S6 but then sold them with a complete kit and went with the Macan because having the plate to put the S4 logo looked way better behind the wheel. https://uploads.tapatalk-cdn.com/20230621/459b22ae99fa0820a61215ae14e90869.jpg

I honestly don’t recall the part number, it is the 14” rears, the E-brake motors are the same so plugs in or you can swap yours if you find them without.

10 Pistons???? I thought it was 6 on each caliper in the Front?? I could be wrong [confused]

[SwankPeRFection]

It’s 10. 5 smaller ones on each side. They’re not as large as the 6 piston ones, but smaller and apply more spread out pressure on the larger pads. You can see them in the pics.

[B18b1ex]

Using the 420x40mm rotor is a mistake and will cost overall performance. I think they weight more than 46lbs of rotational mass, more than any a mass of each front. Other than looks, there’s probably no need to even do that one.

Hey, what shields are you running with the S6 rotors in the back of your car? Do S6 shields bolt right up no mod to the B8 S4 mounting points?

I’m running 2017+ Porsche macan turbo p/n 95B-615-611-A & 95B-615-612-A painted black so that they don’t look larger than the front rotors

You're right, for B8 is overkill. However, in the C7 this set will work perfectly.

For anyone looking to do the 4M Q7 caliper upgrade on their B8 S4 with the half inch spacers, I purchased these titanium (chitanium) 95mm bolts from AliExpress and they were perfect.

Also, here are some other things I purchased for the the setup:

I’ll take the criticism, not really ashamed of it to be honest. Difficult to find a 95mm bolt of this spec made in the US and didn’t really want to cut longer ones. Most stuff unfortunately seems to be imported from China regardless. Seller was highly rated and the quality seems solid. Gonna keep an eye on the bolts over time.

Why RS4 b7 lines?

One of the earlier posts in this thread brought it up. The B7 RS4 lines have a 90 degree elbow that makes it easier to install them. B8 lines have a long straight connection to the caliper.

Just snagged some for my 4M / B8 Avant build. Thanks for the link. Killer price as well. Stoptech resells these exact same ones for $15+ more.

I have a pair of the 4M calipers. In an effort to get them to fit under stock 18’s (my winter wheels) - I am wondering if the following would be possible…

Q7 (4m) rotor - 375x36 w/ 57mm hat height.

Then spacer between caliper and bracket to get the correct height. And finally , a spacer (washer) to go between the caliper bracket and the knuckle to make up the 5mm difference in hat offset.

Would this work? Really looking forward to this upgrade - hoping to get the 375 rotor size to work! TIA!

…EDIT…. Just realized the “spacer insertion” I proposed above would not work due to how the caliper mounts to the knuckle. The bracket would need to be shaved or flipped to make this work….or I’d have to go with a custom bracket as others have done.
…I may just go for the 380’s and see if the 18’s will fit. I “measured” it out and looks like there may be a few mm clearance. :)

Can the 4M calipers be used with a rotor that is 34mm wide?

Wondering if anyone has used the 4M calipers with rs5 (365x34) disks?

I was thinking the original rotor size was 380x36!

Trying to clear 18” winter wheels. The 380mm rotor is a bit too close for comfort.

I don’t have a custom bracket so I’m limited to stock rotor height (52mm).

Ultimately I’m wondering if the rs5 rotor (365x34x52) would work with an appropriate spacer on the bracket?

Sorry it is 375x36mm. I went back in my notes.

I have never tried an 18 because I’m in SoFl. [emoji846] but it appears there may be space to fit an 18”. Here are some photo. https://uploads.tapatalk-cdn.com/20240601/ffc80d6fe6ad1e63b128185c528f4480.jpg

Just test fitted and my 18’s do fit!!!! I had to reduce the size of my “spacer”. Rotor doesn’t scrape the caliper and caliper doesn’t scrape wheel barrel. I have a 15mm wheel spacer. Spokes clear no problem. Probably about 2-3mm clearance between the caliper and barrel. Safe?? My 19” S5 rotor wheels clear no problem. Looks like the 380 may work out after all.

If I could go to a 375mm rotor I would be fine but the rotor hat height would be a problem.

The rs5 rotor would be perfect at 365mm. Hat height is correct at 52mm. The only issue would be that the rotor thickness is 34mm instead of 36mm.

Does anyone know if the front calipers from the A6 c8/4k are the same as the Q7 4m calipers?

Also same for front rotors? both fit 375x36mm?

[MetalMan]

This is a great thread! For better or worse it's caused me to collect parts to go 380mm / 356mm on my 2011 A4 Avant.

For the front caliper bracket spacers I went with 9/16" (14.3mm) height from here: https://www.ebay.com/itm/125195972133 ~$17 + tax

Not including dust shields I'm coming in right at $1k for everything front + rear including C7 S6 rear calipers. Those are from a 2018 so I'm hoping that EPB is compatible with my B8.0.

I see @shreddykreuger posted the Porsche Macan rear dust shields.

Has anyone at this point determined a suitable front dust shield?

For the rears, I kept my stock dust shields - just had to hammer/bend them back a bit to get them to clear the rotor face.

For the fronts, I ended up finding cheap 11-18 Audi A6,A7, A8,Q5,SQ5 dust shields. They bolted up just fine but still needed to be trimmed to fit.

You can also just use your stock front shields trimmed to fit. https://uploads.tapatalk-cdn.com/20240920/9af696ed0a5ae58a8d9018c595e84ef6.jpg

Awesome, you've laid out some very budget-friendly dust shield options, haha. I appreciate it!

What setup do you have that fit 18s? And which 18s fit? I have a Stoptech 380 kit and want to find a way to fit 18 for Winter shoes.

[SNice]

…so they fit but safety is a concern. There is about 2mm between the wheel barrel and the outer edge of the caliper. If a pebble or debris got caught between there, it would tear up the caliper and wheel barrel.

Once I painted the calipers the 2mm clearance was reduced even more. So yes they fit, but I wouldn’t run them due to safety concerns. So… I either need to find an 18” wheel with a wider barrel or limit myself to 19”+ wheels.

18” stock wheel:
334211

19” Wheel (S5 Rotor):
334212

[LaZyB0ne]

Anyone have any advice for taking the caliper apart?

I can't for the life of me get the 7 point inner Spline bolt off. They don't want to budge.



Update: I was able to finally get them off using an impact drill

Related question.... hopefully someone is still lurking that might know.


I actually have a 2017 Q7 and someone suggested I might be able to use the 380mm SQ5 rotors since the Q7 ones are so steep in price.
I compared measurements and all is correct (obviously 380mm vs the 375) with one exception. The height is 52.6 on the SQ5 rotor and 57mm on the specs I found from Zimmermann for the actual Q7 rotor.
Would that make my pad rub and or not fit?

This is all assuming the specs are listed correctly on the sites I found, etc. I don't know lots about brakes, but apparently you lot do. LOL.

It's been several months in the making, but I'm finally driving on this setup:

4M Q7 front calipers with custom ~14mm spacers, SQ5 380mm rotors, trimmed stock dust shields
C7 S6 calipers/carriers & rotors 356mm, EPB brake works perfectly on my B8.0 (VCDS confirmed), bent-inwards stock dust shields


Custom CNC-machined spacers that are fastened to the 4M Q7 brackets:

Front calipers & rotors, hard to see the calipers when painted black:

Rear C7 S6 setup, also hard to see painted black:

I’ve never tried to fit it but seeing how to use the B9 RS five rotor I needed to move the Q seven caliper about 6+ millimeters in board to get it to work without grinding with my brackets. I don’t think it should fit.

Apologies for bringing back an old thread, but I have an 8R Audi SQ5 with 380mm rotors. I recently picked up a set of SQ7 calipers along with 400mm rotors. What spacer size would I need for this setup?
