Hi Guys,

I have an 04 350z Roadster (convertible) with the 18" wheels. I'm looking to upgrade my wheels however, having troubles finding the correct size. I believe I currently have wheels which are 18x8 both front and back. I'm not having much luck finding nice wheels with these sizes. A lot of the ones i'm finding are 8.5" front 9.5" back...and wider - can anyone help me in telling me if I were to get wheels that are wider than what I currently have (and keep same tires 225/45/18front 245/45/18 back) will there be any negative effects on the performance of the car?

Any information would be awesome!

Thanks!
