Camber is -1.6deg. Do you think adding a little bit the tires will wear on the inside too much? Are the steeda spacers any different than the Mr. Gasket ones?
Can you use a coil spring spacer to fix the problem on a SportPlus install? I only need about another 0.5-1.0 inch. I have NT555G2 305/30ZR20 and they rub ever so slightly.
