Mazdaspeed3 Side Motor Mount Combo
The Damond Motorsports Side Motor Mount Combo is a must have for any Mazdaspeed3 enthusiast looking to keep their powertain 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 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 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 PMM/TMM specs:
- Made in the U.S.A.
- Machined aluminum bushing carrier, anodized gold or black
- Lower mount base and 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.

Installed both in 3.5hrs on my 2007 mazdaspeed 3 with a buddy. Noise Vibration and Harshness have increased a bit, especially with low RPMs. HOWEVER, I feel exponentially more connected to the motor and my acceleration and deceleration is super smooth now. Absolutely love it, because Racecar.
Needed the mounts to be able to put it my new engine in and they were on back order but as soon as they got some in they gave me a quick shipping and was here faster then I expected I called to make sure to have it delivered soon I was very happy with the product and the service thank you !
This combo is amazing, easy installation and you notice the difference in response right away best product for the money! I highly recommend them.
I bought these to replace the worn-out stock side mounts on my 2011 Mazdaspeed3. The quality of the bushings and machined metal is very nice, especially when compared to the stock mounts. And the install instructions were pretty good. I already had all the recommended/optional tools for the job, so I had everything ready before I began. I would recommend they fix some of the info/typos in the instructions and update the picture about relocating the grounding wire. It took a moment to interpret. I eventually found the timing cover bolt to screw the wire onto and torqued it to 8 ft lbs.
There was an increase in noise and vibration when I first started the car after the install. But the car feels planted when I shift gears and accelerate. And the car sounds more “solid”, according to my wife. I’ve now driven over 100 miles with these new mounts, and the extra noise and vibrations have decreased quite a bit. They’re still noisier than the stock mounts, but I’m assuming they’ll quiet down a little more after a few hundred miles. It still makes my car a great daily driver.
The previous owner of my car replaced the stock rear motor mount with a Corksport one, so I didn’t bother replacing it again. Because of this I wasn’t really dealing with torque steer, and I’m definitely not now. I’ve had my Mazdaspeed3 for several years and kept it stock, except for an aftermarket Corksport Cold Air Intake. I do my own scheduled maintenance and I don't replace parts unless they’re broken or worn out. I don’t track my car. I’m listing these things so you know what kind of customer I am.
I recommend these mounts because they are high quality and seem to make less noise/vibration than most other aftermarket mounts. The vibrations go away quicker than the extra noise. I bought them over the OEM mounts because they seem very durable -- they probably won’t need to be replaced over the life of the car. My only gripe about the mounts is I feel they were a little too expensive. While I don’t have a problem paying that kind of money, I just expected them to cost closer to $400 for the pair. But I know I paid for shipping, good customer service, and some nice installation guides. I’m just cheap sometimes, haha. But I know paying more for quality car parts is often better than buying whatever is cheapest.
I’m a happy customer. Thanks again! :-)
Mounts came in very fast. Easy install and they work amazing.
