| Still looks over-wheeled IMO. Not to say it isn't awesome, but overwheeled nonetheless. In all honesty, aside from issues fitting brakes under 17" wheels (which you shouldn't really have given that I've seen people run Audi RS6 8-pots and 380mm disks under 17s) I can't think of a single reason to go 18 over an equivalent width and design 17. Less unsprung weight, less rotating mass. |
For some reason, prepared class E36 guys seem to like 285/30R18's. You can get Hoosier A6's and R6's in 275/35R17's and 295/35R17's but no 285's. Maybe there's something special about the compound in that size (sometimes they stay sticky all the way through and thus are optimal to shave down) or it just seems to be the the most optimal size for a go-fast E36. Either way, it's what's popular to race. It just seems to work.
Either way, I always try to limit myself to going no taller than 1" over the top tier trim level of a certain range. At that point it doesn't look too bad. Since M3's come with 17's, I don't think 18's look overly big so long as you compensate tire size with it. Really if offset and overall diameter and width are the same, I see no reason why there should be any fitment issues with 18's on an E36. For instance, 235/40R17 is the stock size for an M3. A 235/35R18 is basically the same size in every dimension.
