These wheel spacers are complete junk. The way that they are designed puts all the stress on the bolts that you screw onto the studs. Not long after installing these one of the bolts snaped and also broke the wheel spacer itself, I had to buy a new wheel as well because before the bolt snap it got loose and started wobbling which damaged the holes on the wheel. DO NOT BUY THESE!!!
Bought these and took them to my local hop up shop to install. They claim the material is too soft and compressed on installation making for wheel balancing issues. Ordered billet spacers instead and installed myself. They work great and easy to install. I didn't confirm myself, so just going on their word.
What is the difference between 3/90 and 3/100?
