I currently have 740M wheels 275/45/R20 with 35mm offset. I believe the 21" 818M wheels are 295/35/R21 with 31mm offset. According to the numbers, this wheel will poke out 23mm more than the current 740Ms?!? That seems to be a lot considering the spacer numbers that I see people using.
Has anyone put 818s on their 40i or 60i? Is there a difference in between the full M and non m cars, because there doesnt seem to be drastic wheel poke on X5ms i have seen.
