Difficult to describe these! But everyone knows what they are and what they do. Often bent during a frontal or rear end crash, these torque brackets, brace plates or whatever you want to call em are critical to the longevity of the gearbox and the diff. They ensure accurate alignment and importantly, secure the diff when accelerating hard. This has been removed from a straight, I crashed 1995 MX5 1.8 with a 6 speed but will also interchange with the 5 speed gearbox. The Mazda MX5 NA Gearbox and Diff Mount Torque Stiffening Arm is a high-quality aftermarket part designed specifically for the Mazda MX5 NA model. This stiffening arm is essential for reducing engine vibration and improving overall performance, especially for models with a 1840cc engine size and 5 gears. Made by the trusted brand Mazda, this part is a reliable upgrade for enhancing the handling and durability of your vehicle. Buyer to collect please.
