I was wondering if anybody is running wheel spacers with either the 18" G35 coupe wheels or the 350z touring wheels on a 5th gen, especially in the rear. I know both wheels are 18x8 with a 30mm offset so I would think most are probably not running any spacers.

Also, for those of you with either of these two wheels on a 5th gen, how close to flush are these wheels in the front/back? Most of the pictures I have seen look pretty close, but the fronts appear to be slightly further out than the rears. Why do so many people choose to run spacers only in the back; is it just for appearance reasons?

Also, from where would you guys recommend getting 10mm spacers? The only ones I have found are made by Eibach for about $130 at autopartswarehouse.com

I have a set of 350 Z stock rims and they sit flush... there is no need for wheel spacers

Well mine sit flush in the front (almost too much for my taste) but if I look at the car from certain angles the front tires are clearly more pushed out than the rear tires. All the wheels are the same as well as the tires on the wheels.

the problem is, if you push them out any farther in the rear, you WILL rub on the inside of the fender. You could use spacers if you rolled the fenders.....
