Review on Gorilla Automotive 108 100 2 Centric 100 2Mm by Tim Ram

This is a quality product, just make sure you order the right ones. The ones I received had to have the stock 6 x 5.5 steel truck wheels fitted to the Nissan Frontier. They feel nice and firm, I would imagine they're polycarbonate, they're hard like a thermoset rather than soft and don't warp. However. This is not a product malfunction or defect, you just need to know what you are doing. These things are literal, so if you have center-capped wheels like I do, they're useless to you. I have 108 wheel center and 100 hub. They fit the wheel perfectly, once you add the center cap you can't reattach it. You must physically measure the inside of the center cap to use with caps.
