Jass Performance Fixed Rear Hardtop Brackets (Miata/MX5 NC)
These fixed hardtop brackets are engineered to secure the rear of the Mazda MX5 NC OEM hardtop. They replace the stock rear latches, creating a tight, secure metal-to-metal connection between the hardtop and the car chassis. This firm fix reduces body twist, enhancing vehicle rigidity and providing a coupe-like structural Functionality. Both material options are precisely manufactured (CNC cut and bent) for direct fitment.
