did some searches by finding some mixed info.

just looking for some confirmation regarding the suspension, are both of these cars identical in that aspect?

Ex. If i get 18" rims on a g35x, is it going to have the same stance/height as a g35xS which comes with 18" stock?

 

Yup, the suspension on the X is the same regardless of the Sports package.
X = 17 wheels,
XS = 18 wheels, Bumper

 

Dont forget sport seats, side sills and paddles
As smokie said.. suspension is the same, as are the brakes as well.

 

oOo yeah.... forgot the important stuff... Good call. BTW you can always order paddles after and install them yourself to save yourself some pocket change.

 

thank you.
