The Damond Motorsports Passenger Side Motor Mount is a must have for any Fiesta ST 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 Fiesta ST's, as well as many enthusiast's daily drivers.
The Damond Motorsports PMM 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 base and top pieces.
- CAD designed, and FEA, street, track & rally tested. You can't make enough power to break this thing.
The Damond Motorsports PMM specs:
- Made in the U.S.A.
- Machined aluminum bushing carrier, anodized gold or black
- Lower mount base and top piece are high strength steel welded and powder coated black
- All high grade fasteners and lock nuts
- OTS Energy poly bushings
- Minimal added vibes, along with lots of tire spinning instead of wheel hop.
NEW! Bushing stiffness options!
- Street 70a or Race 88a bushing stiffness now available
- Street bushings are for those looking to keep added NVH to a minimum
- Race bushings are for those wanting the best performance and least engine movement
- Bushing selection currently only applies to the side mounts. In full mount sets, the rear mount uses the "race" bushings

Note: With this mount there will be added NVH over stock, as well as a slight break-in period for NVH to settle.
I bought both the passenger and rear motor mounts in the street format and, in my opinion, suit the car really well (Damond rear replaced a used Mountune one). Throttle response improved which was immediately noticeable, and shifts felt like butter. You get what you pay for and these mounts prove it undeniably. I would highly recommend!
Installed the front motor mount on my fiesta St, and works a treat. Completely killed off the clunk noise I was getting under shifting using the stock mount. The noise in the cabin is a tiny bit louder as you'd expect from a stiffer mount. But not uncomfortable using the street bushes. Installs quickly and easily. Only concern is the design looks less sturdy than the original, 2 out of 3 bolts to the chassis (one failing would be baaaad) and the fabrication is a little rough with a lot of welding.
Thank you for your feedback! We tested the 2 bolt frame mounting design on rally cars, so we saw no need to add in the 3rd mostly superficial mounting point.
Ok here is the deal this concept is great. The design is well thought out and it does what its supposed to do. Things I would change and I do have experience in engine and trans mounts on RWD cars. First off the base of the mount is a bit on the heavy side of things. It also could be tied into the third bolt hole for the stock mount which the current base is not. Whether or not that really has an overall effect on possible lateral movement ? Who knows it would take detailed tests to find out.
I think with a little thought it could be made lighter though. Also the top of the mount could be made of a block of CNC’d aluminum and come in a lot a lighter with no welds( which were a bit sloppy) Considering the fact the factory mount for the car the top is machined cast aluminum. Do not get me wrong the mount works great and does its job superbly. Their is a bit of NVH if you run Air. Without its negligible at best. In that sense its quite livable. It eliminated a lot of TQ steer with my S280 on my pump gas tune. With the E30 tune I have a bit but nothing compared to the failing Powerflex insert it replaced. lol Time for LSD! hahahahaha
I do like it even with these thoughts and critiques. No one else on the market looked at the mount and took this approach with engine and Torque dynamics like these guys did.
Thanks for the feedback. We tested these mounts on rally cars, and the 3rd mounting point was not needed. If we used a machined aluminum piece for the top, it would actually be heavier(due to the thickness needed), and add about $50 to the cost of the mount. Surprised you thought the welds were sloppy? It's MIG welded steel, it's not going to win a beauty contest, but we wouldn't call them sloppy.
This thing is solid.. beautifully manufactured and aesthetically selectable. Does it’s job wonderfully. Quite an increase in NVH but that’s to be expected. Was an easy install and had perfect instructions with all the details you need including torque specs etc. I was in a bind when I ordered this, my stock mount was broken and Damond came through with LIGHTNING fast accommodations and even made a point to get me the right color bushing while not even stocked. They made it happen! I can’t stress how incredible this company is. I love supporting Damond because they take care of their customers, no holds bar. Excellent piece and excellent company. Look no further. Car feels much more planted, acceleration better, traction better, and somehow my exhaust actually sounds better with it installed. Win win.
I had the amazing opportunity to run this mount for several months during the beta testing phase. I must say I was absolutely blown away with the fit and finish of the mount! 11/10 I originally ran a mountune rmm with stock uppers on my 400whp fiesta on the street and at the track! I had alot of issues with that setup alone launching and the engine sounded like it was comming threw the firewall launching hard. I installed the damond pss mm and took it to the track! My issues with engine movement where solved! I was so impressed with the performance of the pss mm alone I messaged damond and ordered a rear engine mount to replace the mountune mount! I put these mounts threw the paces and threw more then most people ever will at them without one issue! Damond literally told me to try and break it! Thats how confident in there product they are and it does not disappoint! If your in the market for engine mounts damond is your go to! Top Quality parts at a good price with the real world testing to back them up! 🤙
