Product Details

Looking to plant power to the ground, reduce drivetrain slop, drastically lessen wheel hop, all while adding minimal NVH? Look no further, Damond Motorsports has the answer in the DM PMM for the Mazdaspeed3.   

The Damond Motorsports PMM 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 base and top piece.  
  • CAD designed, and FEA, and street tested.  You can't make enough power to break this thing.

The Damond Motorsports PMM specs:
  • 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 nylon lock nuts
  • OTS Energy poly bushings
  • Minimal added vibes, along with lots of tire spinning instead of wheel hop
  • OPTIONAL: Super high grade 14.9 timing cover studs for only $5 more

PSMM what difference

My factory mount gave out two weeks after purchasing my Speed used. A huge difference the mount made. I do feel quite a bit more vibration throughout the car and my exhaust noise is more distinct inside the car. However, it helped with shifting so much I can wait to get a transmission mount. I have driven about 500 miles on it so far and the vibration is not as bad but you don't buy this expecting it to be like stock either. Couldn't be happier with my purchase!

Best side mount

This is a must have with the rmm, great mount and great design. DM has the best mounts on the market!


It’s a great brother and quality

Great Mount

This is a solid PMM. Installation was a breeze and the benefits were immediately noticable. Getting power to the ground is a lot smoother even under normal driving. Shifting also seems a lot smoother. Increase in NVH was very minimal, and would not be noticeable to anyone who doesn't drive my car often like I do. Overall I highly recommend.

Solid mount

Replaced stock mount because it was leaking. Installation was straight forward but I wish there was a better solution for the grounding wire on a Gen1. I did get the extra timing cover studs but didn’t end up using them. Driving impressions after one week. Overall driving and shifting feel are much improved, engine seems to move a lot less and transfer power to the ground better. However, there is more noise and vibrations, at idle and under power, because this is such a solid piece.
