The stock motor mounts deflect as torque moves through the drivetrain, allowing the motor and trans assembly to move. These bolt-through style polyurethane motor mounts will eliminate virtually all of the movement of the engine under load – increasing power transfer to the rear wheels. Our exclusive design is stronger than the OEM mount, incorporates the correct height and mounting angle, consists of multiple parts and is fully rebuildable. Proper heat-shielding is required on the right side mount. The material used for the trans mount location(s) should match the material used for the engine mounts. Motor Mount Set, Poly 75D for BMW F30 (335, 340), F32 (435, 440), F80 (M3), F82 (M4), F22 (235, 240) and F87 (M2).

These extremely hard race-spec 75D durometer polyurethane motor 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.

AKG uses 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.

Recommended Use: RACE / TRACK

NVH Increase: Medium (These mounts will create NVH at idle and up to about 1000 RPM)
