KSP 1" Wheel Spacers for Nissan 350Z 370Z, 4pcs 5X4.5”Forged Spacer Fit Infinit G35 G37 FX35, 25mm Thick 5x114.3 Bolt Pattern M12x1.25 Thread Pitch 66.1mm Hub Bore Wheel Spacer for Altima Maxima

Super solid and well built, I put them on my 2011 g37s coupe about 1,000 miles ago and have had no issues of any kind. They were easy to install and the nuts that come with the spacers DO fit on the OEM studs so if you have the OEM lug nuts that won’t fit between the wheel and the spacer don’t worry because you can stillUse the OEM lug nuts to hold the wheel to the spacer and the spacer lug nuts to hold the spacer to the hub. Overall Everything fit great, happy with my purchase

Easy install fit perfectly , before and after shown. Super satisfied.

I put these on the day after recieving them. Very easy to install and they feel very nice and sturdy. I like the KSP logo on them, they look sporty. I fit these onto my 2012 Nissan Altima Sedan. I'll update how they do for me. So far, loving them.

I've had these on the rear of my 350z for 3 years.

I have used generic spacers before and after using KSP will never do so again! Excellent quality and no vibrations at speed!!

The Thread on the spacers won’t allow you to bolt in the wheel on one side the other side was perfect

I bought one each of the 1" and 1/2" spacers with the intention of using the 1" on the rear, 1/2" on the front. The rear spacers went on without an issue, but the wheels won't go on factory studs with the 1/2" spacers installed. Those spacers come with new longer studs, but no instructions on how to swap studs. YouTube videos for this process show people using expensive pneumatic equipment or working on cars with exposed rear wheel hubs (which I don't have).Moral of all this is, if you want to install spacers the 1" ones are easy as pie and quick. The 1/2" studs will require a visit to the shop or a friend with specialized tools.

Nice quality, good machining and packaging
