In Reply to: Anyone using E36 M3 wheels? posted by Doug on December 20, 1999 at 12:19:53:
E36 M3 wheels will work on an E30 M3 with 10mm hubcentric spacers front and rear - with correspondingly longer lug nuts of course. I'm told by my shop the 8.5" rears will fit - as this is what I want to do too - but I have not tested this size. 15 x 7.5's all around is no problem. Spacer kits available from BMP, TMS etc.
Tires: 215/40-17, 225/40-17 (correct diameter) or 235/40-17 (diameter slightly larger than stock)
