Bushings for SuperMiata Competition Motor Mounts


Product Description

Replacement Bushings for SuperMiata Race Motor Mounts (full set, 4 bushings)

The 70D bushings will vibrate the car more than OEM style mounts, but are noticeably smoother than 88D and 95D durometers. The 88D and 95D durometers are only recommended for 100% drag or drift cars due to their harsh vibration. The B series Miata engines are not smooth, so using a stiff mount improves shifting, at the cost of everything else shaking. These 70D bushings are the best compromise for precise shifts.

In comparison to the 75A rubber Mazda Competition mounts, the USA made SuperMiata Race Motor Mount replaces the entire oem hardware with a steel powder coated mount while incorporating a 70D urethane bushing to reduce engine/trans deflection more than any oem style mount. The SuperMiata Race Mounts will last longer and are servicable. SuperMiata Mounts only need service every few years instead of  full replacement annualy like a tradional rubber mount.

Torque spec on mount through bolt: 50 ft lbs
