The AZ Race Mounts are the Exact saem CNC Machined Copy of the Hasports. The reason is, I got 3 mount with the kit, and I could on use 2 cause the one that is supposed to go to the rear was never hooked to anything. So let me know what I need to get to hook the rear one up. I am SURE my car will drive hella better wit ha Stron polyurethane mount in the back.
