AKG Performance Parts for BMW

Motor Mount Set, Poly 75D (BMW E30 M3)

Part#: MM303

Product Description

Motor Mount Set, Poly 75D for BMW E30 M3. The stock motor mounts deflect as torque moves through the drivetrain, allowing the motor and trans assembly to move. These straight bolt-through polyurethane motor mounts will eliminate virtually all of the movement of the engine under load – increasing power transfer to the rear wheels. Proper heat-shielding is required on the right side mount. Not to be combined with factory (OEM) trans mounts. Can be used with our Group N Trans Mount Set #GNTM3. 

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.

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). Straight bolt-through design. Hardware Included. Engineered for a perfect fit. Read why our polyurethane mounts are the highest quality mounts available.
