Z3 wheels onto an e30 m3

[erik325i]

Does anybody know what is the Z3 centerbore?
Does the m3 have the same centerbore as the non-m e30 (57.1mm) or is it different?

The wheels are 16x7 et40, so I will probably need a 15-20mm spacer to fit it onto my m3. Can anybody tell me for sure exactly what size/centerbore I will need?

Both cars have a 72.56mm CB.

The only 5x120 BMW not to have that CB is the E39/X5, which are 74.1mm.

Cool, thanks.
Do you know what the ideal offset for an e30 m3 with 16x7 rims? I will probably just be running 225s.

What Mystikal said .

Plus I've seen pics of an M3 with the M Roadstar wheels .

Same as non-m's; ~ET25

I'd run deeper offsets with M fenders. Like ET15-ET20 at least, for good looks.

Factory 16x7.5" wheels were ET20, for reference.

Thanks for all the help Mystikal!
