Product Details

The Damond Motorsports Full Motor Mount Set 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 RMM/PMM/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 PMM/TMM bases, and top PMM/TMM pieces. 
  • CAD designed, and FEA, and street/track tested. You can't make enough power to break this thing.

The Damond Motorsports RMM/PMM/TMM specs: 

  • Made in the U.S.A.
  • Machined aluminum bushing carrier, and RMM, anodized gold or black
  • PMM/TMM lower mount bases and PMM/TMM top bases are high strength steel welded, and super thick gloss black powder coating
  • 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.

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

I was skeptical for how they would be once broken in just because when they were freshly installed starting in 1st was rough, but now that the motor mounts are broken in its an incredibly smooth drive now

Great performance but not much comfort.

The performance of these mounts are great. The engine barely moves when I rev it or change into gear. However, I do have to testify that it is much more stiff and "rough" than OEM. I know that since it's an aftermarket mount it will be more stiff but I didn't think it'd be this stiff, the whole dash vibrates and shakes the cups/bottles in the cupholder when I rev on first from 1k to 2k rpm. Other than that, the mounts are great.

They're great

The NVH is definitely increased but its easily tolerable and in fact, enjoyable. These were installed on my DD. They make a noticeable difference in wheel hop in in dry weather and traction in wet conditions. I am very pleased with my purchase. Install was fairly simple by myself.

Awesome doesn't even begin to describe it!

I've had two Mazdaspeed 3 Gen 2s in my life; one a 2011 Tech, and the current 2012 Tech; and I've done motor mounts on both. However, the 2011 was just the rear mount and I didn't even know about Damond back then so it was a Cobb unit, and it definitely helped with keeping everything feeling more planted but it pales in comparison to the full Damond set.

Initial impressions were as expected with running full Race inserts with the normal amount of increased noise and vibration before everything bedded in, and now with around 400 miles on the car since install they've quieted down a good bit.

The whole front end feel completely solid now, and my only issues are from increased power causing torque steer which I will be correcting with new bushings soon enough (also available from Damond...check em out!)

I'm running a CST4 with some additional supporting mods and putting out an estimated 300-330 at the wheels, and the only weak link in the front end at this point is the OE suspension components.

The engine DOES NOT MOVE. These mounts do exactly what they say they'll do and quite frankly the amount of noise they cause isn't even really noticeable on my car with the additional exhaust note already generated from my other mods (Cobb catted DP, external WG, etc.)
Personally I do hear a light rattling at idle but it fades out once you're driving normally, and I cannot honestly say if it's from the mounts or if it's clutch chatter from the 6-puck, but either way it isn't bad.

All in all if you're looking for a way to pretty much immobilize your engine without going to a full set of solid mounts, this is the route to go.

Can't wait to get the rest of the car dialed in to really take advantage of these awesome mounts!

Another well made product.
