How much do they rub??? Could you grind down the caliper with a grinder??? That would save you from buying another set of rims, if the caliper is painted you would have to repaint them but that shouldn't be to hard to do yourself and no one would ever know, I know of some guys that had to do that to get there wheels to fit
I would prefer not to grind down the factory calipers. My 14†rally’s do not rub. I will probably use a spacer. But I only need two 15x8 rims if they would clear.
