I have a 2008 350Z Touring with Nismo Suspension.

I am looking at Enkei Racing GTC01

This is just a picture of the wheel if you don't know what they look like, not where I am looking at purchasing from.

18x8.5", 30mm offset front

18x10", 22mm offset rear

I see all kinds of setups with 1" difference front to rear, but I haven't seen many 1.5". Are there any negatives to this, possibly handling wise? Should I not do this? Any suggestions or opinions would be greatly appreciated. Thanks.

 

Why not!

 

Since david didnt answer your question,

Yes, having a staggered setup does affect your handling. Having a meatier rear tire will produce more understeer characteristics. In my experience I think it feels a bit less flickable. Of course, its not the wheel width that matters, its the width of your tires.
