Rear Brake Rotor Clearance

Hi all,

I’m upgrading all 4 rotors and was curious what the biggest rotor size is that will give enough clearance for the rear rotors. The stock spec is 330mm, but I have found some rotors at a good price but they’re 356mm.

Will 356mm rotors fit?

I think you’d definitely have to have a custom caliper spacer. The Stock C5 RS6 uses the same front rotor size and offset, in the rear it uses a 335mm rotor with basically the same caliper. I’ve been meaning to see if the offset is any different but only 5mm larger isn’t going to get you much.
