I guys,

I have a 2004 cavalier with

kyb gr2 shocks
Eibach pro kit springs
17'' fast wheel rims model tension

I find my rims a little heavy and would like to know if any of you have a similar setup but with 15'' rims and what tire and size are you using. I know it won't looks as good but I wan't to get back the power I lost. Do any of you know's how much does weight a black OEM factory rim? and is this size good for my car 205/50/15?

thanks
