For what it's worth I will probably end up running 8mm spacers in the front and 15mm in the rear.
Well the OEM RC's are 17x7.5 et43 soo, you can push them out to a et35 and be safe.....get 40mm bolts run a 8mm spacer up front and a 10 or 12.5mm spacer in the rear and you will be just fine....i know all OEM audi wheels are ball seat...and since the RC's are OEM issued wheels im pretty sure they are a ball seat and not conical seat wheel.

btw if you roll the front fenders....you can run a 15mm spacer up front and a 20mm in the rear with 235's and still not rub and still have room.
