I've done some searching and it appears 18x8.5 and 18x10 can be made to work (looking at BBS Chs). Is there anyone running this combo that can tell me the appropriate offsets for the wheels? I'm considering 225-40 and 245-35 tires with rolled fender lips if required.
Another combo I'm considering is the E36 M3 Contour wheels - anyone with photos? What spacers for this fitment?

Thanks in advance for any info.....

Hmmm. 10's in the rear? I think I heard somewhere that this is the reason that these M3's came with wider fenders. I have heard of some people running 10's in the rear but I"m not sure of the offset. I'd like to know this info as well. Good luck man.
