17in vs. 18in wheels
OK...I'm about to purchase a new 07 si coupe and i was thinking about whether to get the 17in. HFP wheels or the 18in. HFP wheels. I've heard that the 17in. is better for performance, but how much better. I'm just not sure if I want the 18's cuz they fill out better or the 17's cuz they perform better. What are yall's thoughts on this?
