Those are the A5 S-Line package rims, and would probably be pretty expensive. Not really worth it IMO. For the price you can probably find a comparable set of aftermarket rims that are lighter, and more unique. (Plus you won't have to deal with people asking why you have Audi A5 wheels on your BMW.)
Don't cross the streams.
