17's aren't that big and they are fine for racing/quarter mile.... IF they are light.
Heavy rims are your enemy if you race your car. Companies like Rays Engineering, Work, Mugen and Spoon spends huge amounts of money developing wheels that are lightweight. These are the wheels you want if you race and want decent looking rims.
If you got an EG 15" is the "optimun" wheel size for track and street. A larger wheel will not only add unsprung weight to your car but also increase rotating mass. Both of these will hinder acceleration and handling. But dont believe me just do it yourself...chuck a set of 17" chromies on and take them off. Then throw sum stock steelies and tell us how different it feels.
I went from 16" ANZ assasins :? to stock steelies and difference was very noticible. Now just waiting for my new set
