So I've never done any major modifications on my cars besides a K&N filter charger, exhaust, and tinted windows.

I"m going to modify my g37.

I really like the vossen 083 but I've read some comments about them being a "one piece cast wheel"-

So what does that mean? is that bad? what is the difference btw cast, forged....one piece,two piece, 3 piece wheels?

BTW, I think those vossen 083 look sick on a OB G37s
