320 mm or 325 mm

[Jlastor]

I will need to do my brakes in yhe near future so i started doing my research, kindda. Looking at ECS i see many 320mm and 325mm rotors. Which is the proper size for zhp's?

A friend of mine has a set of slightly used m3 rotors from his can from his csl upgraden. Could this fit our cars? I could save some cash if it is possible to run those rotors.

Thanks!

325x25mm is the front size for the ZHP and all other 330i's (E46). Rears are 320x22mm.
I do not believe that the M3 rotors can be swapped without making some modifications, and you wouldn't get any performance benefit anyway.

I also wouldn't buy ANY used rotors or pads. Always get new, IMO. That's a safety issue, and you want to make sure that the rotors match the pads they were used with to avoid any potential issues.
