Some guy at a shop in L.A. told me that the Hartge Classic 18X8.5's don't fit that well on the 540, but that the 19's fit the best. HUH? Does anyone have experience with these wheels? Any problems? Should i consider a different one? I'm an aggressive driver, my thought is that 18's would be better for me? I could use a little help. I want to make an informed choice. (my mother would be proud..lol) Maybe just stick with 17's??
