i'm looking at buying some rims. they are 18" enkei with low profile tires on them. The fronts are something that i can't remember and the rear are yokohoma with about 10 - 15 % left. they want 750 for the set? is that too much? it's local so i don't have to have them shipped. should i go with 18's or with 17's. i don't know if 18's will rub or not, and like the way they look. i don't know, help me out with some advice here. thanks.
