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:

  • Made in the U.S.A.
  • Machined aluminum bushing carrier, anodized gold or black
  • Lower mount base and top base are high strength steel welded, and powder coated black
  • All high grade fasteners, and lock nuts
  • OTS Energy poly bushings
  • Minimal added vibes, along with lots of tire spinning instead of wheel hop.

NEW! Bushing stiffness options! 

  • Street 70a or Race 88a bushing stiffness now available
  • Street bushings are for those looking to keep added NVH to a minimum
  • Race bushings are for those wanting the best performance and least engine movement
  • Bushing selection currently only applies to the side mounts. In full mount sets, the rear mount uses the "race" bushings

Fantastic mount work great

Jared Harper
Absolutely love this mount

This mount is amazing! I purchased the street bushings. I have this installed in a 2011 speed 3. There are next to zero vibrations inside the vehicle other than on decel. The tires feel well planted. There is a little clutch noise now inside the vehicle. Highly recommend this mount. My shifts feel more crisp too.

TMM = great feel and performance

I didn’t install myself this time so I can’t touch on install. I can feel the results, my car feels great. I daily my Gen 2 speed3 and the NVH is not worse and but the car feels way better than stock. I love my car feeling more solid because the engagement is significantly better. The street bushings are the way to go. I have all 3 mounts now. RMM, PMM, and TMM. All street bushings. They are my favorite mod thus far.

Better than Corksport

I had a Corksport TMM and I had a used Damond PMM that came with my Speed3, the USED Damond PMM had at least 40k miles (under my ownership) before it tore. The CS TMM I bought brand new failed in 25k miles of my ownership as the design of the CS TMM is perpendicular to the inertia of the vehicle movement which expanded the spacing between the bushing and the bracket that holds the mount. In addition, while it’s somewhat tedious to have the proper tools to assemble a motor mount in general, having the mount in pieces makes the installation so much easier and less geometrically challenging; the CS TMM removal was challenging as their design isn’t disassembly/removal friendly which means you gotta improvise just to install/disassemble the CS TMM. Bottom line from my PERSONAL experience with the TMM selection, DAMOND MS > CORKSPORT.

Solid, rock soild and zero vibration!

In just 9 months after new Fidanza flywheel the stock had completely blown apart and wasn't conected to anything but the bolt, pieces of rubber everywhere! Had clunks, knocks, slop and the car darted all over cause the tranny was moving so much!!! DON'T WAIT LIKE ME and just get it and see how much more power to the ground, zero wheel hop and so solid as I said!!! AWESOME BABY!!!!!!!!
