I have alot of exper. in rims and tires, and when you start redrilling, changing offsets, and outside tire dimensions, your asking for trouble. If it works out, and sometimes it does, then great, but if it doesn't your stuck with a set of redrilled rims that you don't want to use and probably can't sell. SKperformance is right. Arrising issues can be range from rim movement, speed wobble, broken lugs, accessive bearing wear, etc.etc.( I actually knew a guy who cracked a spacer, and snapped lugs going over railroad tracks!! after I told him the rims he wanted are going to be trouble.) I try to avoid wheel spacers at all costs. And I recomend that to everyone. So over the years, I have come to the conlclusion if the rims don't fit, they don't fit. It's usually not worth the risks.
