i want wheels that look good, but i dont want to totally hinder my performance on the street.. im looking at some of the black 18 inch 5zigen pro N1 wheels... but will 18s hurt a launch that bad? im also bout to get some porgress springs with 1.8 inch drop.... i want something to look good but i am about performance, i just think 17s might look too small.... for all who wanna see the wheel http://www.wheelmax.com/Wheels/5zigen/5zigen.html just go there and scroll down to the black pro n1s.. hope they look good on my silver GS
