Question:Wheels/Brake system for C7 S7

[GWPRO]

Hello, I’m going for 2013 C7 S7 & wondering if the following parts could fit directly on S7 from my current B8.5 S5.
1. 20inch HRE wheels(someone told me that could fit S7 without any problems, tire size:275/30/20, is it true?)
2. Audi ceramic brake system from B8.5 RS5, the S7 I’m considering now also equipped 20inch wheels as well, even my HRE could not fit S7 at least would like to switch that brake system on to it.

Thank you if someone can give some information/advice.

Best Regards,

Wheel size will depend on offset and width. Tires size will work, but 275/35/20 is a better fit on the S7.
