you might need spacers on the front, might not. I do know that a rear 350Z wheel fits the front perfectly. On the rear, a rear 350z wheel needs a 15-25mm spacer.
These are 4 rear 350z wheels that I had widened to 9.5", but widening was to the inside, so unwidened would look exactly the same. No spacer in front and 25mm in rear.
