Im hoping my car detailing buisiness will get me some serious cash this spring/summer so with that money im looking to get a 70's project car, doesnt matter the year in there nor the style because ive got plans for a completely built 350 ect....what I do want to stand out a lot would be the rims. I was looking at some american racing chrome rims. either 18 or 20 inch, not sure if the 20's would be to large so thats why I have the 18's as backup. Anyway on to my real question(sorry) I know rear drive cars need wider rims, so what is the largest I could go in width without modding the body pannels or having them stick out, thanks.
