OEM brake upgrade for 3.0T?

Here’s an animated gif since I can’t upload the video.

If it’s really that significant it may cause issues with the way the caliper works. The rotor should be centered between the pads. In theory if the offset is to skewed to one side you could get over-distention of the pistons.

Does anybody have a picture of how the OE rotors sit with the Q5 Brembos mounted?

Finally got mine installed using the stock size 347mm rotors w/ the Macan calipers & new SS brake lines from the S4/Q5. Only issue is that the brake dust shields doesn’t fit w/ the calipers so the shop took it out. I’ll probably get new ones later on. Here’s a pic as a reference.

Alex .. 6 months in, how are liking the macan 4 pot calipers ?

If it’s as easy as swapping out lines, pads & calipers , this is a very practical performance upgrade. Thanks.

I second the question! Looking at brake upgrades myself. I live in a rocky mountain state at the base of some fairly pretty mountains. I frequently do some canyon runs that can be pretty hard on the brakes, and I'm looking for something to handle the heat better.

Seems the consensus is that the Q5/Macan 4 pot calipers are a good option, and they fit with the OEM size/thickness rotors? However im assuming as it would be stock rotor size, you wouldn't be looking at better thermal management? Or would the calipers + slotted rotors make a difference?

Very interested in the results as well...

**ewmin3m** · 02-04-2021 09:12 PM

This is a great thread; can't wait to get this done on my 3.0T wagon as well :D Thanks folks for all the infos.

What is the cost for this, does anyone know off the top of their head?

I have a set of calipers, hawk pads and lines. 600 shipped to your door. 500 for calipers only

PM me if you are interested. You will need to buy S6 discs.

Bolted right on. Just can’t used the stock dust shields without some cutting

Hey. I saw the details you posted on Facebook. I'm also trying to choose between the Q5 or the Porsche Macan. Thanks. I'll ask you one question. Q5 Which of the two is lighter in the weight of the Brembo and Porsche Macan brakes?

Pretty sure the Macan Calipers are about 12 lbs and the Q5 are 9 lbs. I sacrificed 3 lbs for the cool factor :-)

Hi NAS are these a direct bolt on for the A6 C6 or is there anything else needed? Thanks.

From my research , you need S6 spindles as well for 09-11 C6. Previous years might be direct.

Can confirm that the brake calipers from RS6 C6 are plug and play for A6 C6 with 3.0TFSI ;)

Hi I may now go for the Q5 Brembo set up will these bolt straight onto my 2007 A6 C6? What exactly will I need to make these work? Thanks.

I don’t know about an 07 , the calipers require the 347mm rotors so if those are what you have then it is a direct bolt on.

But I tough your fronts are Front rotors 320mm so the Q5 / Macan upgrade won’t fit. The S6 are a straight swap as far as I know though.

Could I not just get the 347mm rotors and then this set up will work? Also do you need the Q5 lines or will the A6 C6 lines work on these calipers? Thanks.

You need the Q5 lines. I don’t know if you can mount the 347 or not, the issue is your spindles are different from the 3.0T so I don’t know if the calipers will bolt on correctly.

Hi what exactly is needed to fit the Q5 brembo calipers to an A6 C6? I've just bought a set of calipers thank you.

Apparently the S6 calipers bolt straight onto my car so I'm just hoping these Q5 calipers will bolt straight on.
What model and year Q5 do I need the lines from? Thanks.

So you know , the S6 and Q5 calipers are totally different. I have a set of S6 ones. You need calipers from a 3.0t Q5. Not sure what years. ECS and fcp both have kits

Awesome which is a better set up in your eyes the S6 or the Q5 brembo?

I went with the Macan calipers for the cool factor but the braking power of the calipers are about the same.

These are the S6 ones I have for sale

- includes pads and lines & should bolt up to your current rotors.

**dluxxx** · 04-17-2021 11:00 PM

do you guys have specifics for what year Q5 or Macan? Don't wanna buy the wrong year.

Pretty sure any B8 Q5 with the 3.0T. For the Macan calipers , I bought for a 2015 with 345mm rotors.

There is a full parts list in another thread I posted.

Does anyone have the proper part number for the crossover line on the Q5 brembo calipers. i found a recently rebuilt set but they dont have the lines.
thanks

**ewmin3m** · 04-26-2021 11:22 AM

Just a suggestion, you should ty to get a braided stainless steel set instead of OEM.

i did order braided steel lines to the caliper. i am looking for the part number for the crossover line. the hard line that carries fluid from one side of the caliper to the other.

**ewmin3m** · 04-26-2021 10:18 PM

Ahh nice :D cool.

At the end maybe you can post a parts # list to have it on this thread as well :D

Can't wait to see how it looks

looks like there is no replacement option offered by Audi. will call Porsche monday and see if they have an option for the macan. unfortunately this turned a cheaper rebuilt alternative into a still cheaper then new but more pain in the ass. oh well. i will post what i find from Porsche.

**a1dan_87** · 08-13-2021 08:36 AM

That brake upgrade is looking closer and closer for me. I need to do the brake fluid (Had it boil, whoops), and I think I had a pad or caliper that's sticking, so now is as good a time as any. Audi lists the 8R0615107G and 8R0615108G as for the A7/S7/RS7, Q5 and SQ5. 345mm brembo calipers, and this thread confirmed they fit OEM 347MM sized rotors.

So consensus is, with new brake lines, that Q5/SQ5/Macan 4 pot brembo calipers will bolt straight up to our cars?

Seems like it.

I'm wondering if there is an adverse effect on braking system; if the calipers are designed for smaller rotors and you put a big one.

Though as I'm writing i see the difference between the two is 2mm so i'm guessing it shouldn't be too bad.

Where do people get the stainless steel lines ?

Also does anybody know if the 4 pot brembo calipers wider than stock A6 calipers? I'm only asking to see if i would have to swap wheels or not...

Hey, been meaning to reply to this tread for a while but got really sick, surgery, relapse, dr’s… life is finally getting better. This is literally the first time I’ve had a chance to get on the zine in a long while. Got a lot of reading to do.

Anyway, there is an 18z option that bolts right up without mod’n the towers. It takes a bit of parts sourcing and milling of the mounts but the math works out and I have probably 7,000 miles on them now.
I’ll gather up the build pics and specs and post back shortly.
Not implying that this is any better than the Macon setup, just another option that works optimally with the OEM m/c

These are some pics I found on tablet.
