My suspicion is that they will, as the standard 330ci will take CSLs, no? :?
I know it'll look odd, but, this isn't a permenant change, it's just something to keep the car on the road while the alloys that my wife has just decimated are refurbished!
Genuine CSL's won't fit a 330, neither will M3 wheels. The rear offsets are different. Not sure about the Z4M wheels, what offset are the rear wheels??
