Mazdaspeed3 Full Motor Mount Set
The Damond Motorsports Full Motor Mount Set for the Mazdaspeed3 is here! Get your car fully mounted with our specially designed mounts that hold the motor solidly in place while adding only minimal levels NVH.
New RMM redesign and lower price!
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:
-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.
I didn’t buy all three mounts at the same time. I wish I did and I wish it was an option at the time. I was grabbing the mounts as they were released. I put over 75k miles on all three mounts. Totals: rmm 94k, pmm 80k and tmm 75k. Numbers are rounded down. Over the years I’ve done numerous Hpde’s, autocross events, wintercross events and even a half mile shootout. With 75k on the mounts the engine barely moves on start up. Bushings show zero signs of fatigue or needing replacement. With the Damond mounts I don’t have to worry about failure. I know they won’t.
I am in love with the quality of the mounts, they are great!
Better than expected. Great install instructions.
So i changed out the Passenger Motor Mount (had the corksport one before) and the Tranny mount, I really want to give it 5 stars, the first hundred miles vibrations were minimal and it felt solid, real well planted. Im wondering if something perhaps got loose, so ill have to check and then update late.
Going from all stock mounts with a blown passenger side to all 3 Damond mounts. I'm very happy with my purchase. High quality product that does actually come with detailed online instructions on the website you're reading this on. I didn't know there was instructions but they really do help a lot. I used a car jack with a piece of wood and installed them 1 at a time. Both side mounts took me 1-2 hours each and the rear mount takes like 30 minutes. These big bolts are really tight so put on your big boy pants. The noise and vibration is pretty gnarly at first but as the mounts settle in after a few hundred miles (please drive safely), they mellow out a little bit. I like the race car feel. If you like a plush ride maybe just get the rear mount. But overall for my application and my definition of comfortable, they aren't too bad to daily drive.
