AKG Motorsport BMW F8X M3 / M4 75D Poly Transmission Mount Set
The stock trans mounts deflect as torque moves through the drivetrain, allowing the motor and trans assembly to move. These bolt-through polyurethane trans mounts will eliminate virtually all of the movement of the trans under load – increasing power transfer to the rear wheels. The material used for the trans mount location(s) should match the material used for the engine mounts. Trans Mount Set, Poly 75D for BMW E30, E36, E46, E82, E90, E92, F22, F30, F32, F80, F82, F22, F87, Z3, Z4.
These extremely hard race-spec 75D durometer polyurethane transmission mounts are the hardest available (aside from solid aluminum) and the best option for race classes where solid mounts are not allowed, or for those who do not wish to deal with the issues that may arise when using solid mounts.
Our U.S. Military Spec 75D durometer compound is as hard as a bowling ball, yet has elasticity and memory. This exclusive compound allows us to manufacture a mount that has virtually the same performance as a solid motor mount without the harshness on the brackets/chassis associated with solid mounts. Likewise, its elasticity and memory means they are also free from deformation which plastic mounts (Delrin, UHMW) are very prone to.
Made of our exclusive U.S. Military Spec polyurethane (75D hardness). Bolt-Through. Hardware Included. Engineered for a perfect fit.
