Product Details

Our Formidable Mazdaspeed3 Rear Motor Mount is now lighter, more compact, easier to install, and best of all... Now available at a lower price! 

The Damond Motorsports Rear Motor Mount is a must have for any car enthusiast seeking to plant power more directly to the pavement.  While material was removed on this latest revision, we validated the strength of the newly designed mount with FEA analysis and track testing.  This new Mazdaspeed3 mount also happens to be the same mount we offer for the Focus ST & RS, which means we can offer it for a lower price than before.  

If you're looking for a no compromise rear motor mount that will drastically reduce wheel hop and engine movement, improve shifting and clutch pedal feel, this is the mount for you.

The Damond Motorsports RMM starts life as a solid chunk of alloyed aluminum.  Once it’s machined to size we add a pair of off the shelf bushings sourced from the market leader of polyurethane bushings.  These bushings are arranged so they only see compressive loads, as they are designed for. No twisting, no bending, and no edge loading mean that the bushings will have a long and productive life. 

Available in Black or Gold anodize with Black or Red bushings.  Included are high grade fasteners.

Note: There is added NVH with this mount. One bushing has a relief shaved off, this is to allow fitment on multiple vehicles, and does not effect performance.

It Works! Hella stiff

So this rear motor mount works. That’s forsure. Fitment is 100%

Now it’s suuuuper stiff coming from a stock style motor mount.

Fits well.

No more loud clunk thump while shifting fast.
No more wheel hop.

Lots of vibes in the beginning but it’s starting to calm down after 100 miles. They say it’s way better after 500 miles so we will see once I hit that.

Other than that it’s cool.

Good stuff!


Install was quick and easy! Definitely louder inside the car but I like it. Car feels a lot tighter with a lot less bounce from the engine when driving. Very happy with my new RMM and would recommend it to anyone looking to add one of these to their ride.

Definitely Worth It

I was debating this one and a few others, and this was recommended to have less NVH than the rest. The NVH is noticeable, but not annoying at all, in fact, after it’s broken in, I rarely even notice the vibration anymore! Made a huge difference in my engine’s behavior, it responds better, and has much sharper shifting. It even improved my car’s cornering capabilities, which I wasn’t initially expecting at all. It’s definitely more than worth the cost if you don’t mind the (minimal) extra vibrations.

Best quality

Best RMM there is, just bought the PMM nect is the TMM

Beautiful piece of work

Replaced a dilapidated other brand rmm that just didn’t hold up, crisper shifts and got rid of some clunk. Great product. But it.
