Hi these OEM rims came off an RS6 Wagon and I'm putting them onto an S5 Coupe
They are 20 x 9.5 ET 36
The cb is 57 so will have them cnc machined out to the correct 66.6
Any ideas if I have this correct for best fit I think they need
275 30 tyres
15mm spacers up front
20mm spacers at back
Car has standard suspension
