will 2006 18" go right on a 2005 enthusiast with 17" with no problems and or mods. they are also a bit more wide?

 

Shouldn't be a problem...

 

You can put any OEM Z or G35 Coupe wheels on your Z in place of the 17s...

They'll be fine.

Even the 18" Front/19" Rear combo they are putting on the new Gradn Tourings or whatever will fit. Those are some nice wheels too (Rays Forged).

 

thanks Zman, will that throw off the speedometer, anything else?

 

I don’t see why not. All 350Z wheels are interchangeable. The limiting factor is Brembo brakes. I would not assume that all OEM 17 inch wheels fit Brembo.

BTW the most expensive used OEM wheels are the forged Rays. I have seen these wheels sell on eBay for $1,600/4.

 

I have yet to see the NEW forged Rays for sale on ebay, although I've been looking...
These are the 18" front/19" rear ones on some of the top-end 06's. Also I believe they are on the black Z in the Z commercial (the one with weird music).

You can usually pick up a set of 03-05 track wheels for 1000 without tires. I've seen them go 800-1200, so I'll take the average.

Davidv, if you are interested I know a guy with a set of track wheels AND 90% tread on the tires. He is asking $1300 or so I think as he is getting the heavy anniversary wheels. He is my dealer... let me know. I thought about it, but if I get OEM forged wheels I'm going for the Inifiniti G35 19s...

 

I've heard even the stock 17" wheels clear the Brembos, so I think any wheel will go on any model just fine.

 

Yup, they do.
I've seen a few use the 17" rim for their winter tires and the brembos definitely clear.

 

I will be posting my 06' stock wheels and tires for sale pretty soon....

 

Man, I want a set of the '06 Track Wheels. I don't know if I am willing to pay the price however. Once money starts rolling back in here; I'll probably bite the bullet. I'll buy them with Goodyear F1-D3's, Koni Sport's and Hotchis sways and call it a present to myself for not being able to buy anything this year.

Then it's Vortech and NOS for the Firebird. Ah..... one can dream.
