They fit perfectly, are high quality and really fixed the way my model 3 looks!
These spacers get rid of the sunken look that the stock wheels have, and instead make it flush with the side of the car. The lugnuts are special and ensure there is enough thread to engage the nuts even with the spacer installed. The spacers fit perfectly on the hub and in the wheel with a tight tolerance, it's almost an interference fit. These spacers save weight by allowing you to still use the factory studs and you wont have to worry about the factory studs keeping the wheel from being tightened by sticking out and interfering with the wheel.
