Fiesta ST Passenger Side Motor Mount
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.
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! 🤙
For years I've wanted this kind of assurance in my engine bay. I beat the crap out of my Fiesta ST Offroad and I need to be sure my engine is safe at 5k RPM launches. Couldn't be happier! Several very rough events down and zero issues! Only go with these, take it from me.
I had the chance to test the product in beta production. I had never bought a Damond Motorsport product before but many of my friends own Mazdaspeeds and they love these motor mounts.
Once the product was ordered, the shipping was very fast, despite living in Canada and considering the delays due to the pandemic. At first glance the packaging, the welds and the quality of the materials were on point. The instructions were clear, being a mechanic I expected some information to be missing but it was really complete. Despite having received a piece welded in the wrong direction, customer service answered me within minutes and I received the right piece within a week. May I remind you I am from Canada and shipping was very quick.
In the first place at idle, the car vibrates more but that is to be expected when buying this type of product. (little tip: if it vibrates too much for you, try loosening the bolts and retightening them, maybe the engine pushes against the support). I use my vehicle for time attack. Basically, the car is full bolt on, turbo s280 313whp. I'm really rough with the car and it never gave up. The side motor mount is a must. According to my experience, it made the rev match easier, less wheel hop, better clutch feeling and better throttle response. Since the motor flexes less there is less energy absorbed by the support and it goes directly to the wheels. (I am not an engineer :D ) I advise anyone who wants to improve their driving experience to buy the motor mount. I hope Damond Motorsport will develop an engine mount for the transmission as well. I will buy it for sure.
