After browsing the net for almost 2 hours, I finally found two rims that may look good on the Z. However I need some opinion on which rims should i go. Picture is attached. The first one is Buddy Club and the bigger picture is CR.

1. Racing hart CR 2pc 19x8.5 and 19x9.5 (nice looking but little bit heavy)

2. Buddy Club P1 II 19x8.5 and 19x9.5 (lightweight not as nice as CR)

both of the rims has +38 offset for the front and rear.
Let me know what you think.

 

Volk's TE/LE37 - the only way to go

 

Imola Design 22 are the sweetest! But they are pricey.

Since you probably missed these, I wanted to give you some more options, as opposed to what the poster below says.

Is it possible to take the paint off the factory 18"ers and make them polished aluminum instead of that silver paint color, like the show car had at detroit?

 

Definitely the first ones. No question.

 

Go for Buddy Club! Those wheels are featherlight, almost, if not lighter than the TE37s...
