I just thought I'd post a pic of this before I get a set of stock wheels to sell my car. A buddy of mine let me use his stock G35 wheels untill I find a set of my own.
Going from the I-forged to these hurts, although I think if I never had the I-forged that these wouldn't be so bad. The only thing that really needs work is the offset(spacers may do the trick). I personally think it looks a lot better than the stock touring wheels

 

they do fit the car very well in terms of looks.

 

Yes, they were the OEM wheels on the early G35 coupe 6speed with the brembos(I think they only came on the manual).

 

If you need a set of stock 18s from an 06 roadster hit me up. Very good rubber still etc. oh yeah pricing to sell.

 

They match very well for the Z.
