Making a change from the BBS RC wheels and have sourced a set of Compomotive CX 601, I may have a set in 16'' form soon. I was looking through internet for information about the wheel. In the E30 M3 what was the OEM width and offset. The tires are 225/45/16 assuming because the sidewalls are perpendicular to the wheel they are 7.5J...but the internet only says they came in 7J or 8J form. Confused, any help would be great. I'm thinking of running them on my E36.
For reference here is the wheel, this isn't the ones I'm looking at
