Does anyone know the offset for 2007 G35x Sedan? i am tring to get some
19" or 20''. Can anyone help me?

 

Stock offset on 17" 07 G35X rims is 45mm

 

thanks would you know if 20''x8.5 40 offset would fit

 

I plan on running 18 x 8.5 with a 42 offset on my X all around.
I think the 20 x 8.5 with a 40mm should be fine for your X.
Thats the thing you should run the same size on the AWD front and rear.
Just to give you an idea of what some others are using, Hikos is running 8.5 x20 x 35mm offset front and 9.5 x 20 x 43mm offset rear on his rwd 07 G35 Sedan.
The 18" OEM wheels for the RWD 07 Sedan are 45mm front and 50mm rear offsets.

 

You're wealth of wheel/offset knowledge Wayne!

Given alot of thought on the topic?

 

Well Andy, I just try and do a lot of research on my own ride which is the 07X, and this info is offered on this site from all the others. If I do get puzzled on wheel fitments, I know I can always call my good friend Chico, our site wheel guru . I swear he has info on every wheel available in his files.
I have had my wheels stacked up in the basement waiting for the warm weather to put them on for a while now.

 

Heh, a waiting game indeed.

I am already getting extremely antsy at the moment.
