I’m looking to upgrade the stock brakes on my 2015 S4, and I was looking to do the C7 A6/A7 caliper upgrade with 356mm rotors. For anyone that has done this, did you have any clearance issues running 18” wheels? Looks like an easy swap and I can get the parts pretty cheap, but would still like to run 18’s for winter. Thanks in advance.

Might as well do the Aluminum B9 S5/S4 caliper with that same 356mm rotor!
But yes, both of these setups should fit under 18in wheels.
On my BMW I ran 370mm under 18s. And the M3/M4 runs 380mm under 18s too. Of course only a few selected 18's fit when running this large of a rotor.
