I hate the stock X5 sport wheel in my 4.6is... aside from being super worn with tattered stitching, it's pretty thin without any of the contouring that I like. I plan to replace my wheel with a good condition M5 one. Clemster over on M5Board parts out tons of M5's so he often has some nice wheels in stock. I got a very nice M5 wheel from him for only $300 that I put in my 540it.
