I have been thinking about going with 4 Rear sport 18s on my sedan. Weight savings will be equated by the additional rubber. Any pics floating around? Should push the wheels our about half an inch. Here are the stock specs:

2007-2008 18" sport wheels
Front: 18x7.5 +45mm offset (appx 23.7lbs)
Rear: 18x8.5 +50mm offset (appx 22.4lbs)

I am guessing the g37xs wheels would have close to the same weight. I would prefer those looks wise.

I am surprised more X drivers are not running this set up.

 

Just remember that any set of XS wheels will be just 4 of the 7.5" (fronts) from the RWD Sport wheels, so if you want that style in the 8.5" (rears), you're going to need to procure the rears from TWO RWD Sport vehicles. (or buy a second pair new = $$$)

 

I have a set of the S wheels I just took off my car; two of the 7.5 and two of the 8.5 all powder coated graphite. I was going with that same setup but really needed tires and couldn't wait to find another 2 of the 8.5's then get them PC'd. So I went with aftermarket. Like the S wheels better.

 

They go for about 600 a set without tires on craigslist. I could get two sets and easily sell the front 4 as x sport wheels. Seems like a cheap way to get some more rubber on the ground and more flush looking wheels without using spacers. I will keep my stock sports for the winter.

 

Yep, that's the best way to do it.

 

I would love to see pics as well since that was the setup I was considering. I just didn't have the time to locate the other 2 rims since my tires were bald on the inner side of both fronts.

 

^^ That's too bad. If you two had found each other before, and shared the costs, you could of worked out one hell of a deal.

 

I know! Haha. O well. I havent bought any yet. I really would like to get the newer body style wheels or the 370z 19" forged fronts. For some reason there are only the 07-08 style up here.

If I end up biting the bullet on the 07-08 I will post pics.
