Hey guys, just recently got my M2, and I love the stock 437M wheels, but looking around I'm seeing some 437M wheels on M4's that were Ferric Grey, which I like much better.

Anyway, I've seen these wheels in so many finishes, from black, to dark grey, to lighter grey, to nearly pure silver. Can anyone tell me what finishes came from the factory, and on what cars? I ask because I'm not interested in rep's.

Thanks in advance for any info.
