all i have to say is wow. i went from a 19lb 17" rim with 205/40/17 tire to a 11.5lb rim with 195/50/15 rubber. so many things are better now, accelleration, braking, ride comfort, steering response ect are all better. now when i hit a bump it doesnt feel like im gonna break something. ride is so smooth. i couldnt believe how much difference dropping almost 8lbs per wheel would make. i was skeptical at first, but now im a believer! in case your wondering i have the 15x6.5 rota circuit 8's in flat black with yokohama avs es100's in 195/50/15. just wnted to share my happiness.
