This spacer was plug and play from start to finish! I installed 370z jet wheels on my 350z and the front ends were rubbing on the upper control arm. So I went with them and they fit perfectly. I didn't even have to cut the stock wheel studs to make them work. Lightweight and durable with a beautiful finish. Very happy with this product and there are no problems. Always remember to add anti-seize between wheel hub and spacer and spacer and rim! This is very important if you don't want to end up knocking out your rim like I've seen in some YouTube videos.
