B5 s4 brake upgrade

[Cbotello]

Might be buying full front and rear s4 brakes with uprights for 300 is that a good price ? Don't really need them now but probably in the future so I don't want to pass on them if the price is good, but don't really know what s4 brakes go for.. I believe they are off of a 2001.. Is that all I would need to do the swap I have a 2000 1.8t manual trans.. I would be getting calipers rotors pads and uprights front and rear for 300.

[Bordom]

1. You don't need uprights for the rear. They bolt right up

2. If the uprights are aluminum, you will need a new lower straight control arm because the balljoints are different between steel and aluminum uprights.

3. You will need either 2001 1.8T front axles or V6 axles to mesh with the upright since the wheel bearing goes from 75mm to 82mm.

$300 is a fair deal for all that. Get him to take out the rear uprights and seal the deal for $200-250. Make sure you get the rear caliper carriers with that otherwise your upgrade won't work as planned

Not worth it. At all!

you are going to be $300 + LCAs and still have really heavy 2 piston cast calipers...and the rears are really not worth the investment. you can get some w8 / c6 v8 rears and have larger (10.5in) VENTED rears.

So, for $500 you can source yourself some; OEM Porsche Boxster calipers, brackets, lines, and a8 rotors and actually have a REAL upgrade.


I wouldnt have anything else on there. not to mention Worlds lighter and more efficient.

[Cbotello]

Ok thanks I won't be getting them in that case.thanks for the info guys

It's a fine setup, better than what you have from the factory (they put it on the S4's for a reason).
Yes you can go bigger, "better", etc., and pay through the nose if you want (the whole "source it yourself" doesn't work as well once everyone is trying to get the same used Porsche parts).
If I recall corectly the A8 stuff is actually in between the A4 and S4 for size.
The biggest bang for your buck you can get is really aggressive pads, just be prepared for more wear.
But if you do go with bigger brakes, whether it be S4 or not, be prepared to face wheel to caliper clearance issues, measure and test for that first.

Oh, really?

You need to know where to look

As for S4 brakes, I wouldn't waste my time on them. If you want something better than stock, go A8 upgrade. If you need something cool, go 17/18z, or wait for a decent deal on a used brembo set or something.

[Cbotello]

Redline where should I look ?

Well, I got s4 uprights from another member on here. They weren't cheap, but he didn't screw me either. I paid $300 for 17z calipers shipped from Rock Auto. They didn't come with crossover pipes, so I had to get some from ECS for $50. I think I bought some cheap pads and rotors from Rock Auto with intentions of upgrading later on, as well as stainless lines from Rock Auto.

So basically, Rock Auto is the answer. Prices for everything now-

17z calipers- $142/piece, so $284
Pads- Lots of options $40 or less, so $40
S60r rotors- There are cheaper options, but I'd go with the high carbon ones for $65/piece, so $130
B7 RS4 Stainless lines- $40
Crossover Pipes- $50 from ECS

We are just shy of $550, make it $600 with shipping. You will also need some bolts and sleeves, so add another $50. So, $650 for the brake setup alone

You will also need brackets or s4 uprights, and depending on the year and engine of your car, you may need axles as well. I think I have about $1000 into my brakes, but that includes the 300mm rear setup as well. Now, if you have time, you can wait for good deals, sales, or your price could go up or down depending on the quality of parts you buy. But there is zero question that I could put 17z calipers on your car for less than $1000, most likely around $800. JHM sells everything listed (not s4 uprights and axles since their kit is for an s4) plus a liter of fluid for $1950. True, they include higher quality parts, but I can piece it together for $1300 less, give or take of course.

What year Porsche Boxster do I need to source these parts from?

Anyone have any info on rear upgrades too?

[redline380]

Pretty sure they use 986 boxster front calipers. not sure though.

What info on rear upgrades do you need? You have two options, essentially- stick with a b5 s4 caliper and the appropriate bracket to go from b5 s4 stock up to 300mm, or go full custom and four piston brembo's from something else. The latter will take your parking brake away though, which is why sticking with b5 s4 calipers is nice.

the guy above mentioned something about w8 / c6 v8 rears and have larger (10.5in) VENTED rears

[redline380]

the guy above mentioned something about w8 / c6 v8 rears and have larger (10.5in) VENTED rears

he meant c5 a6 4.2, btw.

Pretty sure b5 s4's are 256mm for rear brakes, and then you have a few options ranging from s8, w8 passat, 4.2 a6, etc.

Some of these options, and I am not sure which, are not awesome solutions because of slight difference between calipers and such. That is why it is best to stay with s4 claipers, which are essentially the same as a4 rear calipers, only wide enough to fit the vented rotor. Off the top of my head, b5 s4 rotors are 256x22mm. You can freely go up to b6/b7 s4 rear rotors which are 300x22mm with the associated brackets.

[Kronprinz]

^Thanks.

What is the going rate for both 986 front calipers?

[Bordom]

It's funny because B5 S4 rear rotors are vented haha.

Simplest upgrade is the S4 rear upgrade. It's a direct bolt on. From there I would jump straight to the B6/7 S4 rear 300mm rotors like redline380 mentioned. All you need is the brackets (if coming from an S4 upgraded rear)

I would personally (because I eventually will) get the front spindles with some V6 A4 axles, and go straight to 18z calipers with ML55 AMG rotors and a mild pad to compliment it. Track car status haha

[Wrath And Tears]

The A8 upgrade is pretty simple. You just need TT caliper hangers and you use the B5 calipers and pads, with the A8 rotors.

[nautica tuner]

I got the 17z Brembo calipers from the Cayenne. For the pair, you'll probably get it for $450-500 used.

[demonmk2]

The tt\a8 combo with boxter calipers compared to stock calipers is night and day
Fairly inexpensive upgrade too

[demonmk2]

Unless you just like the look or you're pushing a lot of hp big brakes are overkill imo

[Bordom]

Mostly for looks haha

The Cayenne calipers have always been about $500 but then you are pretty much stuck with 18 inch wheels or larger (and despite all the rage, taller wheels are not better for a number of reasons...).
The six piston Touareg calipers are the same but shorter so they will clear some 17 inch wheels but as soon as word got out that you could put them on S4's the price went from $150 to $350 etc. and all the ones in wrecking yards were quickly grabbed up.

S4 rears are a great option, as you yourself mentioned. S4 fronts are better than A4 fronts which is all I stated. Since the OP was mentioning buying the full deal for $300 I simply stated that it was a better setup than he has now and technically it is a good deal.
I bought S4 rears off a salvage company through eBay and the calipers were in need of a rebuild so I kept the carriers and used new calipers instead that JHM gave me a great deal on.
Since I have the aluminum uprights from an early 2000 S4 I just used some cheap S4 fronts rather than deal with the extra cost of fancier calipers and spacers and different rotors etc. etc.
Plus I can still run some 17 inch wheels.

I may not be remembering correctly but aren't the A8 rotors like 288mm vs the S4's 321mm? It's been years since I messed with my brakes.

I've got some of the highest performance street tires out there and I can still get ABS to kick in if I want to do full force braking so any more clamping force isn't going to stop me faster since I'm already at the limit of traction. I also don't have to worry about messing up the braking bias much since I'm running a balance Audi setup (it was quite noticeably rear biased when I only had the S4 rears on and people who have done a front only BBK have mentioned the potential front bias issues). My 2 cents.

[demonmk2]

^Thanks.

300-350

And get the brackets from usrt..

[nynoah]

For anyone that wants S4 rears. Just go to Autozone and buy rebuilt S4 Brakes and then turn in your A4 ones for the deposite back. You will need S4 rear rotors and new pads. But its a cheap upgrade.

The fronts require a lot more work. I have the S4 brakes all around on mine and I really like them. Though I am debating upsizing to the Toureg brakes.

[demonmk2]

^^you pulled it off?

[nynoah]

I just had to replace my rear brake caliper because the parking brake part was seizing. Autozone sent me a caliper with the mounting bracket attached. They took the box back (deposit) with barely even a look. The just looked to see there was a caliper in there. Heck I think I am going to try the same thing with the Taureg brakes and S4 calipers... lol

[Kronprinz]

300-350

I didn't see any brackets for an A4 on their site.

...essentially beating them for rear S4 cores. LOL

[nynoah]

Go to Autozone directly and ask them when you buy if it comes with the brakets. Mine did and when the guy sold them to me he said that the ones I was ordering came with the brackets. He was quite proud to tell me because it was a selling angle to get me to buy it. I was like hmmmmmm. I bet some people would like S4 rears

You got my wheels turning

[Davdraco1]

the ebrake cable lines right up?

[nynoah]

Ebrake lines line up. I have S4 brakes all the way around right now.

[DarthWinja]

+1 for the A8 brakes, I love mine.

[Kronprinz]

So, 312mm rotors, boxster calipers, brackets from usrt(any where else to get brackets, oem or aftermarket?)

TT carriers?

[Wrath And Tears]

http://www.usrallyteam.com/index.php...oducts_id=1893

I think these are the brackets made to fit the TT spindle (upright I assume) also assuming its the same as ours. I did no research as I am not looking to do the upgrade, just went to their site and clicked on the Mk.IV/TT category for braking.

[demonmk2]

Apikol but a lot more money wise...

They'll work, I've done an upgrade using them for the 986 calipers

Dude, v6 Cayenne calipers and any touareg calipers are the same (within a certain amount of years). Those are called 17z calipers and are available rebuilt from rock auto for $142 a piece. And yes, they do fit some 17" wheels. I know because mine fit under my 17" celebration wheels.

The v8 cayenne calipers are called 18z's and use 20mm larger rotors than the 17z's.

Yes and no, the Touareg had two 6 piston caliper sizes, one the same as the Cayenne and one with shorter mounting tabs for a smaller rotor that would fit in a 17 inch wheel, those became scarce and expensive when I was trying to find them, so I gave up. JHM uses the longer mounting tab calipers from/for the Cayenne in their kits, thus the 18 inch wheel restriction. I spoke with them when they were originally building their kit and thinking they could make it work with 17 inch wheels but when all was said and done not only was it 18+ inch only but it also ended up costing about 70-80% more than when I first heard about it. Oh well, like I said, my S4 brakes can do more than the best tires can handle so I don't need more.

[demonmk2]

With TT carriers?

If you want to use your stock calipers the TT carriers will work, if your using 986 calipers the TT adapter carriers will work.

They're two different carriers but both will bolt up to your uprights depending on which caliper you use.

What years exactly should we be looking for those 17z's?

[nynoah]

I am just going to write this because I know someone on here (lurking newbie) is probably thinking about this. So just to be clear 17z WILL NOT FIT AN A4. They must be used with S4 uprights or adapter plates. I would suggest researching a lot before you jump into them.
