Fiesta ST Passenger Side Motor Mount

I needed to change my serpentine belt...that's when I noticed my motor mount was ripped!! So I upgraded to the Diamond mount... and WOW!!! VERY SOLID!! There's a small amount of vibration... but any Motorhead would fully expect that!! I am TOTALLY satisfied and would DEFINITELY recommend this mount to those who have turbo upgrades like Myself. It's worth every penny!! 👌👍

Hurry up and make a drivers side mount please! I love this thing!

I started to hear the dreaded rattling and creaking in reverse and at low speed. After some research I found it’s usually the passenger side motor mount. Happy I went with Damond. Well packaged, part is beautiful, and the instructions were some of the best I’ve used. After the install there is no more creaking, less engine movement, and very little NVH with the 70 durometer. Buy this part, you wont be disappointed.

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.

Installation:
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.

Review:
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.

I would have to say this has been a good mount. Im blown away by the improvement. NVH is minimal with the softer bushing and i barely notice anymore than stock which works out great. Glad to say Im happy with this mount. I currently have it paired with a powerflex driver-side insert.

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.

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.

The Damond passenger side motor mount is a true work of art and belongs on any fiesta that is driven hard on the street or even track raced. The install is very simple and can be completed in just a short amount of time. It’s a very well designed mount and is very strong. Mine survived a impact directly where the mount is located at 100mph into a guard rail 10/10 highly recommend this mount.
