e30 rear, z3 rear (4 cylinder model & MZ3) BUT control arms are different size, doulble check with ->

E36 they all work, the offset (caster i believe) on the M3 is different if i'm correct from other E36'z. I have the 325i setup in front. Some here have the M3 with larger brakes which need larger rims: 17in+.
Check around in the Swap and suspension section to see what others are using, what works and what doesn't. Best of luck!
