Mazdaspeed3 Rear Motor Mount

The best mount. Period

2008 Mazdaspeed3. Was worried about the NVH from the Damond mount, since I was trying to keep NVH at a minimum. After much research and reading tons of threads, I sent it and bought the street stiffness. Install took 30 minutes. It's not bad at all. Minor vibration increase, and can hear a lot of transmission noises. Slight increase in aftermarket exhaust noise as well, but definitely tolerable. Shifting drastically improved. Engine doesn't bounce around like the stock mount. Very good mount. There is a reason people say go for Damond when you choose your motor mounts, and now I understand why.

Seems good so far

Only have a about 50 miles on it since install, but can definitely tell a difference in feel of the car. Only a little bit of extra vibration, but nothing too crazy when cruising.

Couldn't Be Happier

I had recently purchased my MS3 and everything was completely bone stock at 100k miles, RMM included. It almost felt wrong to accelerate with how much the engine was moving. After installing the Damond RMM (and some other bits and pieces) the car feels extremely solid under throttle, a complete night and day difference. The startup NVH was a little higher than anticipated with the 80a bushings but some of that can be attributed to how blown out the OEM mount was. I have absolutely zero complaints and would consider this the best bang for your buck modification if you're still running the OEM RMM.
