Focus ST/RS Side Motor Mount Combo
Focus ST/RS Side Motor Mount Combo
SKU:DMSTSIDEBRR
The Damond Motorsports Side Motor Mount Combo is a must have for any MK3 Focus ST/RS enthusiast looking to keep their powertrain solidly planted, drastically reducing wheel-hop and torque-steer, all while adding less NVH than the competition. Damond Mounts are ran on the quickest most powerful track Focus ST's RS's, as well as many enthusiast's daily drivers.
The Damond Motorsports PMM/TMM design:
- The bushings are oriented 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. Orienting 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.
- All factory mounting points are retained.
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 lock nuts
- OTS Energy poly bushings
- Minimal added vibes, along with lots of tire spinning instead of wheel hop.

Note: With these mounts there will be added NVH over stock, as well as a slight break-in period for NVH to settle. We have removed the front plate from the PMM after further FAE analysis determined it was not needed, which make the mount a bit lighter. Spacers are now included with the PMM instead of studs as well.

Rated Excellent & Trusted

Good quality, instructions were concise and clear step by step with good pictures on Damond's website. Note: Understand that these are polyurethane mounts that change the axis of rotation and isolate movement much better than the OE mount design, so there will be increased NVH even with the Street Duro which I got, mainly on takeoff and off-throttle coastdown in gear, but at idle and while driving are very docile. Overall tradeoff is well worth it for a small increase in NVH (vibration).
Everything was packaged perfectly. Alex was amazing to work with and he made everything a breeze with ordering!
