I'm thinking about getting some 18 inch anthracite FR500's. Right now I have 17x9 inch 2003 chromies around and I was planning on swapping the rear for 10.5. So my first question is should I stay with 17's or go 18's. The only reason I would go for the 18's is for the FR500's. Second question is by looking at the pic below do you think theres enough room for 18's, my car is lowered but I do not know how much.
