My speed 6 had other poly mounts before from a different company and they were genuinely so annoying to drive on the street. It seemed like I could feel if a piece of hair fell onto the motor. Safe to say that got real old real quick. I swapped to damond street mounts and it is worlds better! Still stiff enough for aggressive driving and use, but way more comfortable for daily driving duties! Probably the best nvh change I've done to the car!
Was previously running a higher hp built motor and just a rear mount. Despite stiffening up about every other part of the suspension, the car still felt sloppy, especially when going on and off the power. At one point the engine movement was so bad it broke a weld on my exhaust. That’s when I knew it was time for a change. Ordered this combo with the stiffer race bushings and while they do make the car vibrate more, it’s not unbearable. In fact I like the new raw sound from the motor and gearbox that is fed into the cabin when you get on it. When just cruising around however, it’s not too much more noise. The main benefit is how the car now feels planted and stable. It doesn’t feel shifty anymore in turns under throttle or when making throttle changes, gear changes are more direct, and despite making double the power, torque steer is less than when the car is stock. If you can handle a little bit of race car vibes, these mounts will go a long way in locking down your speed to the pavement. The vibration eases a bit after the mounts break in as well.
Awesome product and fast shipping! Definitely gained a customer for future parts!
I love how my car drives know. Even turning on and off the car has improved dramatically. Shifting gears really improved dramatically also. Its crazy how just the motor mounts improved the ride and handling. Exceptional products.
Personally I would go for the stiffer bushings. Installed the street bushings and while they are a huge improvement, I think stiffer would be better. Also very minimal nvh added, barely noticeable. Just purchased the race bushings to swap in. Damond never fails to impress. Excellent product!
Thanks for your review Cody! We do sell just the bushings if you'd want to switch them to the race ones. By the way, you do have the bushing carrier backwards. I'd suggest getting that corrected before it tears the bushing.

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! :-)
loving these mounts you can really feel the power hitting ground and it makes me want more upgrades! Thanks Damond!! Great design!
I had always had a problem with torque steer,plus the passenger motor mounts are crap on the MS3,mine was busted and the tranny side was barley hold up.I installed these on and fixed all my problems,and did notice the torque steer is almost completely gone.these were pretty easy to install,heads up though for the passenger mount you will have to relocate the ground wire on the passenger mount,and the tranny side is a lil tricky but could be done.
Love them, good quality, easy to install and works great. Car feels more solid now and vibrations aren’t bad at all, not to mention not having worry about the stock pmm blowing out and shooting hydraulic fluid everywhere. Definitely recommend!
Super cool aftermarket part, a definite to get rid of those Junkie OEM motor mounts.
I had been running just the RMM for around a year now and finally got the last two mounts installed. To my surprise the NVH has lessened now that it's not just the RMM absorbing everything, huge win. Shifting the car at the limit feels extremely precise now as almost all slop has been removed from the drivetrain. My only regret is not installing the trilogy to begin with.
Best thing i bought in a long time. must need for your car to feel more solid than ever.
Havent installed yet but just the build quality in itself is amazing i dont think ill have to change another set or motor mounts
Looks good
I have not installed it yet
The vehicle is stored for winter
Made a HUGE difference in power delivery, feels so much smoother to drive. Oh, and if you've only done the rear motor mount on your mazdspeed 3, you're missing out as having the other two smooth out overall resonances at around 3k rpm (well they did for me at least) as you're distributing load more evenly between same type of bushings. I was worried about nvh becoming a problem with all 3 (street stiffness) but to be honest Its not much different from just having the rear, definitely worth the upgrade. Pulls flawlessly now
Easy install, RFV is not as harsh. I purchased the street inserts. I would recommend them. 👌
running them so far for about 300 miles and i love them, even with the race bushings there aren’t too harsh. definitely a great buy if you’re looking to stiffen up the front end or you just need a replacement the street bushings are a wonderful option!
Love them thank you!
Best quality out there for the Mazdaspeed3. Love it easy installation
Quality motor mounts!
Great product highly recommended this combination my MPS is just a totally different car now well made be definitely be using Damond Motor Sports again makes a quite change from CorkSport thanks Damond for a great product .
Love it. Helped against the torque steer. Very good quality. Shout out to customer service for being so responsive and helpful.
Dude… if you’re putting $$$ on your build, do it right! Make the investment & get the mount combo. It’s a huge difference, less wheel hop & torque steer. They take abuse & keep going!
Amazing product!
Will recommend 💯%!
Thought the cabin noise and vibration would be bad but it’s almost like stock but much better feeling! Would def recommend!
