why I suggested 300mm max diameter rotors.

The Q7 has a two piston (or maybe 4) 330mm or 358mm rear setup depending on the motor.

I wonder if the rear bolts up to our factory mount?

From the ETKA sheet it looks like they do not use carriers like most audi's do, but bolt directly on like the front calipers.

which pads did you get for those calipers ? the ones for 330mm rotors (cayenne S ) or the ones for 350mm rotors (cayenne turbo) ? i guess the second.
and these calipers are the same for cayenne S or the turbo correct ?


oh and a place that could make some perfect rotors for these calipers is Coleman ( i think )
Coleman might be able to make a rotor for this setup.

sureface the centerline would be 16.75 unless I am missing something =)

I know this is an old thread, but I just wanted to add updated info to it. I found the perfect rotor to use with 18Z calipers from a Q7/Cayenne. I put this set up on my A4 B7 using MB CLA 45 350mm rotors, only thing needed is opening the center bore to 68mm. Obviously you still need the correct bolts and brake lines, but it gives you the 350mm and allows you to run 18Z pads as well.

Thank you for the additional tech!

And, after13 years, my original rotors are a bit long in the tooth, and I will look for these as a replacement.

So, thank you for helping me out, and also for adding to the body of tech upon which the Audi enthusiast community is built.

Here’s the specs for it, I also found this Q7 one that I think will also work and already has the 68mm center bore. It might be another good option.
