I acquired some 18x10 wheels for the rear of my 2010 M6 RT and have MT 305/45's on them. The rim is just hitting the rear sway bar. Am I right to assume that a spacer, say 0.5" would help take care of this, and give enough clearance, maybe could go smaller, 7/32"? Another question, the only spacers I'm finding are for a 78mm hub, or universal, so would a hub centric ring for 71.5mm hub to 78mm wheel work with the 78mm spacer (wanting to keep everything centered)? I also notice that the hub only protrudes about 0.5" from the front of the rotor hat. So that means, if a 0.5" spacer is used, the wheel is only being supported by the lug studs? Oh, shorter sway bar link would be the solution but I really don't want to go that route. Any advise?
