COBB Rear Motor Mount for all 2014, 2015, 2016, 2017 and 2019 Fiesta STs.

The COBB Rear Motor Mount (892001) incorporates a unique bushing, specifically designed and engineered to improve traction without harshness. Stock engine mounts tend to allow wheel hop and engine movement which are two unwanted occurrences while enthusiastically driving your 2014-2019 Fiesta ST.

This Fiesta ST motor mount is made from 6061 billet aluminum with zinc hardware for an impressive look and a reliable, strong construction. The COBB Rear Motor Mount is the best way to minimize engine movement, improve traction, and reduce wheel hop without a major impact to NVH.

- Machined from 6061 billet aluminum
- Laser etched COBB logo
- Unique molded voids absorb vibration
- Reduce engine movement
- Improve traction and minimize wheel hop

Typical bushing design will rattle your teeth and bones when your newer Fiesta ST is idling or during heavy throttle input. This COBB Rear Motor Mount implements unique voids and recesses that are custom molded into the brawny, 85A durometer bushing to further aid in vibration absorption.

Reduce engine movement and help in getting all the power to the ground with this upgraded, strong rear engine support. Machined 6061 billet aluminum construction makes you sad you have to hide this attractive new mount, but with less noise, vibration or harshness you will surely be smiling wide!

Order this COBB (892001) Rear Motor Mount for your 2014, 2015, 2016, 2017, 2018 or 2019 Fiesta ST from CJ Pony Parts today!

Rated 5 out of 5 by from A must have! This motor mount should be one of the first parts you purchase for your Fiesta ST. The install was very easy and straight forward. I immediately noticed that the shifting became smoother especially under higher RPM's. It also noticeably reduced the torque steer, giving me greater control of the wheel under WOT. I would also like to add that my Fiesta ST is a 2016 model. So for Cobb and the rest of you I will say for a fact that this part is compatible with the 2016 year models with no issues. There is minor vibration at idle just as other customers have stated but this is minimal and I didn't even notice it after the next day.

Rated 5 out of 5 by from IMPROVED! I figured what do I have to loose and made the purchase. It took longer to lift up my car than installing this. As mentioned by other reviews, there's a slight more vibration after it's installation. After two days of normal driving, it went away. I finally started to punch the pedal and my car feels more sturdy. Unlike the OEM, we I was on the gas, my car felt like it something was loose. With the RMM installed, it feels like a new car. The only problem I had was that it didn't come with paper instructions. I watched the video 3 times before I installed it. 20 minute installation time. Torque wrench is required!

Rated 5 out of 5 by from Better engine sound/ More power to the ground I bought the COBB RMM last week and just installed it this weekend. I couldn't be any happier with my recent purchase. The shifting is so much smoother and it adds a lot more power to the ground. The only Con that i could think anyone could say is that it adds a lot of vibration inside the car.. BUT THATS WHAT I LOVE ABOUT IT.. AWESOME

Rated 5 out of 5 by from Perfect! I needed a new mount for my 2008 Mk 6 Fiesta ST and came across this product after some searching. The Mk 6 Fiesta ST has a 2.0L engine rated at 150bhp. Ford also used the standard engine mount with this ST and so the mount didn't last long. Mine was cracked and worn out. The Mk 7 basically used the same mount but with slightly modified bushes. I wanted a mount that I could fit straight in so the COBB RMM seemed like a good choice from what I found. (Looked nice too!) Didn't take too long to arrive (it travelled about 20500 Km in 5 days) and I installed it the day I received it. Quality made and installation was easy with the references they supply. The gear shifts are nice and smooth now when under load and the vibration is a lot less than I had anticipated. Only with the AC on are the vibrations felt more but quite easy to live with. Overall very happy with product and dealing with COBB!

Rated 5 out of 5 by from Nice RMM (Put Power To the Ground) I have installed my Cobb RMM two week ago and I'm really happy of the result!! The installation is really easy. The mount made a huge difference in how the car launches and feels during shifts. No more wheel hop. :) The shifting between the gear is just better!! All the power of the Fiesta ST is put to the Ground with the RMM. There have only one negative point is the added vibration from the engine when idling that the stock mount absorbed. But it is not bad at all and you only notice it when you're idling. Definitely worth living with. Good Product Cobb!!!

Rated 5 out of 5 by from COBB RMM FTW The addition of the COBB rmm to my FiST has made the feel of the clutch so much better. I can feel the car move forward as I release the clutch. I also no longer have the clunk under full throttle shifting. Sure this rmm is more expensive than the bushing inserts that are also on the market, but this is far easier to install (10-15 minutes), it is high quality and looks much better.

Rated 5 out of 5 by from Don't even debate on it. Bought this as one of the first mods on my Fiesta ST. Takes maybe 10-15 minutes to install. Just makes the car feel better. Shifts under acceleration don't jerk the car around. Very little vibration transfer, mainly at idle with the A/C on.

Rated 5 out of 5 by from Simple Upgrade and a must if you are doing other Power Mods Pros: Definitely get less wheel spin, less wheel hop, less torque steer, and smoother shifts vs the stock RMM. I no longer get wheel spin when shifting hard into 2nd or 3rd. I can still get a lot in 1st. In my tests I've been able to put down about 20 ft/lb more torque in 1st and 10 more in 2nd. That's not on a dyno or anything... I use Cobb's AP and Access Tuner Race software. Before installing the RMM, I had spent a considerable amount of time adjusting the Throttle Requested Torque tables for 1st/2nd gear @ 100% throttle (ie during Launch Control & FFS) so that it produced just enough power to accelerate without any wheel spin. Since installing the Cobb RMM I've been able to increase the torque by 20 ft/lb in 1st and 10 ft/lb in 2nd. Also, very easy to install. Cobb has a instruction video on the product page under the description. Take a look... Cons: When driving there is absolutely no added vibration or harshness of any kind. When idling (like at a stoplight) WITHOUT the A/C there is a slight, almost unnoticeable, vibration. Personally I like it; makes the car feel more alive. When stopped, idling with the A/C cranked up to full blast the vibration is just slightly annoying. I wouldn't want to sit like that for 20 minutes, but a minute or two is no big deal. If you have Access Tuner Race you can just bump up your Idle to between 1060-1080 RPMs. I've done this and it cancels 100% of the vibration. I've only been monitoring the coolant and oil temps for a couple days, but so far its all normal. It has been in the upper 80s/low 90s here. If you live somewhere hot and drive in stop and go traffic I would recommend you watch this closely. It will of course have a slight effect on MPG. I haven't had it for long enough to tell for sure, but so far the effect seems very small.

Unfortunately I cannot accurately answer your question. Without the vendor supplying any information regarding fitment for non-US Spec cars and CJ's not having a car to test parts on, we cannot confirm this part working on your vehicle at this time.
