ok, yes i've read the calculator offset thing, so i'm thinking of buying rims that are 17 X 7.5 wide and have a 48mm offset cause its cheap. i know its not going to clear or is it? if not, how much of a spacer do i need? and if i use spacers will they work. I WENT ON TIRES.COM AND CHECKED OUT 17'S FOR FITMENT FOR MY 98 INFINITI I30, THERE IS A RIM THAT IS 17 X 7.5 with a 48 mm offset, but it doesn't seem like its kosher, someone help!!!!!!!!!
