whoosh motorsports 2014-2019 Fiesta ST rear motor mount *Street-Spec*
We have come up with a mount that offers the performance required in a rear mount yet minimal interior vibrations will be noticed.
The whoosh motorsports Fiesta ST Rear Motor Mount utilizes custom molded large end 72A durometer bushings and small end 80A durometer bushings to absorb vibrations. This combination reduces engine movement and improves traction yet doesn't increase NVH (Noise Vibration Harshness) to an unbearable level.

- Laser Etched whoosh motorsports Logo
- 75A Large End / 85A Small End Yellow bushings
- Reduce Engine Movement
- Improve Traction and Minimize Wheel Hop
- Weight - 2 lbs 2 oz.

Should’ve done this earlier lol. Looks cool too
That a $100 part could improve the handling and feel of a car so drastically. The best analogy I have to explain the difference is that the stock RMM makes it feel like your car is being pulled/towed by a stiff bungee when accelerating. Everything feels elastic and unstable. The upgraded RMM on the other hand makes the car feel solid, planted, and stable. All shifts--though 1st to 2nd especially--are smooth and precise. Torque steer is almost non-existent; you'll still feel some under hard acceleration, but it no longer threatens to veer you off the road. And, last but not least, steering feels more responsive overall due to reduced wheel hop.
Now that I've written all of this out, it does make sense how drastic of an improvement this motor mount is over stock. Any car's handling and feel would be improved if the ~300lbs of weight over the front end was no longer allowed to rock back and forth so violently.
Finally, below are a few installation tips, as well as the list of tools I used.
Do the following if you want to minimize NVH:
- Use poly bushing grease on the face of the bushings where they rub against metal.
- Use a jack stand to add light support to the engine/transmission. This helps everything line up correctly during reassembly.
- Use a torque wrench. The 4 bolts (2x lag bolts, 2x stud bolts) that secure the mount should be torqued to ~50ft/lbs, and the remaining 4 locknuts that hold the downpipe bracket should be torqued to ~17ft/lbs.
- Torque down all bolts and locknuts in the order that's pictured.
Tools used:
- 13mm deep well socket
- 3/8 breaker bar
- 3/8 torque wrench
Now, do yourself a favor and buy one of these mounts so that you can enjoy your Fiesta ST that much more!
I was skeptical at first but post install it feels like a whole different car. Replaced my worn stock rmm and now shifts are very crisp and the car feels even more fun to drive and more engaging. Slight increase in vibration but that was expected. Overall fantastic mod, should have done it when I first bought the car. Install was easy as well
Waited a 2 months to review this product because as a person that fixes cars for a living I know a product like this takes time to settle. At first I thought the vibration was a bit much but after a month this product is perfect! Specially for the price.
Great upgrade. Quality and fit perfectly.
