Those wheels are nice. But they will not fit at A5 /S5. If you notice the CB 57.1. It means the Center bore of the wheel. The CB on the A5 S5 is 66.56, standard Audi wheels will not fit.http://www.audizine.com/forum/showthread.php?t=228731
I was looking at the "R8" wheels in this thread - price seems pretty reasonable. Any thoughts?
