Wish the 10mm came with studs already in them but I do recommend these if you’re looking for the fitment.

Ended up not needing... that's a good thing .. my Akebono brake upgrade fits even my stock winter wheels.

I am not certain the tolerances allowed on these spacers for safe vehicle operation. I measured across 5 or 6 points on the spacers and the measurements vary between .003 and .010 of an inch. Compounded accross an 18 inch wheel makes me a little nervous. I have not installed them yet but I may try them out and see how it feels.

We used these spacers on the rear of a 2006 G35 Sedan with 370 sport rotors. The tapered ID of the hub protrudes through the rotor and is a larger diameter than the center hole in the spacer. We had to take a rotary file on an air grinder and taper the center hole so the inside face ID was around 0.2" larger than the outer face ID and then they fit properly. Other than that, flatness and thickness were correct.

Does not fit. Stock wheels are center hub load bearing. This transfers to the lug nuts and studs. Created wheel wobble. Also. They are not prepped for front hubs. You have to drill for a screw that sticks out of the hub.
