Product Description

As used on our National Championship race cars, MiataRoadster Delrin solid motor mounts minimize engine/transmission rotational torque rocking which can cause missed shifts.

Our unique design is round, eliminating any need to clock the position of a rectangular shaped mount.

Compared to both the factory’s standard and "competition" rubber motor mounts, MiataRoadster Delrin mounts are superior because:
• Delrin doesn’t break down from contact with the petroleum-based fluids (gas and oil) present in the engine bay.
• Delrin doesn’t break down from the extreme heat of the engine, exhaust manifold, turbo, and exhaust.

Due to increased noise, vibration, and harshness that will be transmitted to the interior of the car, we only recommend our solid motor mounts for use on dedicated race cars. (For street cars, check out the AWR urethane mounts which are available in three hardnesses.)
