I managed to pick up a set of genuine RS6's (18" 8.0Jx18H2 ET43 Ronal 1291 - from an A6 - only £100 so worth a try) recently for my A3 ('05 TDI Sport -17" Stars 7.5Jx17H2 ET56 Ronal 1132). Having looked at a few threads, I calculated that they should fit OK (extend 17mm more using a wheel calculator) as others had fitted them, but before buying tyres and fitting them, I thought I would try one on the front of the car. To my surprise the wheel looked daft as it stuck out beyond the wheel arch. Now I know it didn't have a tyre on and the car was jacked so I won't get the true look, but the wheel did seem to stick out much further than I expected. Has anybody else fitted this size of wheel to an A3? Most pictures are taken side on so don't show how far the wheel extends. I wanted to avoid buying the tyres and then finding out they still look daft.
