I used these 2" spacers to mount Hummer wheels on a 1988 Chevy V30. They fit perfectly and look like a VERY well made product. On the plus side they contain the flimsy nuts that are needed to attach them to the car, then your stock nuts attach the wheel to the spacer. You don't need to purchase anything to use these pads. However, a 3" wide spacer would be the ideal width for my application. Check well as they cannot be returned once installed.
