Damond Mazdaspeed3 Transmission Motor Mount



The Damond Motorsports Transmission Mount is a must have for any Mazdaspeed3 enthusiast looking to keep their powertrain solidly planted while adding less NVH than the competition. Damond Mounts are ran on the quickest 1/4 mile record setting Mazdaspeed3s, as well as many enthusiast’s daily driver Mazdaspeeds.


The Damond Motorsports TMM design:

The bushings are orientated properly to support the motor and absorb vibrations across the whole bushing.
This allows us to use stiff bushings without increasing NVH to unbearable levels. Orientating the bushing carrier in a transverse manner further reduces NVH, as less stress is put on bushing flanges.
Full length welded steel.
CAD designed, and FEA, and street/track tested. You can’t make enough power to break this thing.

The Damond Motorsports TMM specs:
