Looking at selling my 20inch forgestars from my e92 m3 to a friend which has a c63 ! Would they fit? Since they are both 5x112?

Not sure about Benz, however on BMW we run 5x120. Also, doubt they will fit, offsets for our rides are more aggressive. NON-M 3 series would run fine on a C63 I'd bet...if the bolt pattern were to be the same.

Bolt pattern is not the same. 5x120 for BMW, 5x112 for Mercedes. BMW bolt pattern is different from all other German makes. MBZ, Audi, VW are generally 5x112. Some of the older/smaller VW/Audi are 5x100. Porsche is 5x130. The Audi Q7/VW Touareg are 5x130 b/c they are based on the Porsche Cayenne.

There are some Acuras that take the 5x120, but they generally use higher offsets than the BMW calls for. Some GM cars, like the previous generation Camaro, use 5x4.75", which is 5x120.65mm. These can generally interchange, though offset may be an issue there as well.

Thanks Ben!
