This is my second set I have bought from this company and I can 100% say their spacers are quality. My first set were 2 inch 6x5.5 bushings, I ran them for about a year and a half and finally decided to rub them every day. I ended up pulling the trigger and getting 1.5 inches hoping that would solve the problem, not completely but I can say I'm doing a full turn more than before. My aftermarket wheels have rear dents so I didn't have to cut the studs, but just because I didn't have to doesn't mean others will be as lucky. Tighten to the specs of the lugs and your kit! I would highly recommend this company's pads to anyone. As I said this is only my second pair just to try a new size, my 2 inches are still perfect and easily ready for the exchange I would like
