OKAY, now i am going to do this come march, so i need my time to research. I got the pro kit and kyb's now i need some good rubber. My question is, if i was to keep the stock rims and throw the kuhmo ecsta supra 712's on them, how much of a handling loss would i have compared to the 18x7.5 rims? 205 55 16's vs 225 40 18. I want to how the tires roll is on the 16's? I think someone out there has the stock setup. Help me out guys......
