They did fit without hitting the calipers, but they look undersized and I wish they stuck out more in the back, would probably look better if the car were lowered about 1 inch. I believe I will probably go with 19's on there, just not sure what wheels to get yet.
Now I am a lazy person. I did not put all four on there, just two to see what it would look like, so the 19s are still on the other side. But at least I know they will fit. I will probably be selling these Nismos with Michelin tires in the near future.

height difference (Nismos on car)
lots of clearance around calipers on front
and rear
One clean 370Z and one, eh, Twin Turbo Z that could use a bath.
