Off the top of my head for that spec wheel: 12mm is a pretty safe bet, 15mm may be pushing it, 20mm would probably require rolling the fenders.
What spacer would you recommend on a pre lci e92 xdrive with msport 193m's 18inch? Tires are stock RF at 255/40/18 rear and 225/45/18 front?
Will 15mm rear and 12 front be ok? or if i want to upgrade to the 313s at 19" set up will 12mm rear and 10 front be a better option? thanks
