Product Description

COBB Rear Motor Mount for all 2013, 2014, 2015 and 2016 Focus STs.

Stock engine mounts tend to allow wheel hop and engine movement, two unwanted occurrences while enthusiastically driving your beloved 2013-2016 Focus ST. The COBB Rear Motor Mount incorporates a unique bushing, specifically designed and engineered to improve traction without harshness.

This 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 major impact to NVH.

Typical bushing design will rattle your teeth and bones when your Focus 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.

COBB is an automotive engineering company dedicated to developing solutions that increase the driving experience and vehicle performance. COBB approaches design by taking the entire vehicle-platform into account as a complete system. Their premium value products are professionally engineered, thoroughly tested and backed to make sure that they meet and exceed customer expectations.

COBB Motor Mount Rear Focus ST 2013-2016 is rated 4.625 out of 5 by 48.
Rated 5 out of 5 by from Great build, great price I've had this on my gen 2 MS3 for almost a month now. So much better than oem! Shifts are smoother, no more knocking noise when slamming through the gears and the torque steer is greatly reduced (I'm sure replacing the passenger mount would pretty much do away with it). There is more NVH but for me it's only been in a small portion of the rpm band (1700-2400) and it's not really bad. I actually like the noise. Install was super easy. Conclusion: If you want your car to shift the way it should have from the factory, get more power to the wheels and still have a comfortable ride I would highly recommend this mount.

Rated 5 out of 5 by from Great Upgrade! I know that this product is intended for the ST, but when I started getting �the bang� in my Naturally Aspired 2013 Focus SE, I decided to upgrade my mounts. I got a TTR upper mount first. It fixed some of the issues, but there was still some wheel hop and the bang was still there. I bought the Cobb mount, problem solved. Wheel hop totally gone, no bang whatsoever, it even reduced the vibrations I was feeling after installing the TTR upper mount. For those of you not 100% satisfied with the Cobb mount alone, get the TTR Upper one too. Together they are awesome! Great Product!

Rated 5 out of 5 by from Great Results First thing, definitely feel the difference right after the install. I didn't have much torque steer given having a strut bar and lowered..but my wheel hop was still pretty bad. Especially when it was colder out. You can feel the difference in the handling, wheel hop, and even the little torque steer I may have had. Feels great. Only flaw I would say, since I have turbo back I did notice after the install the vibrations in lower rpm/idle range increased. But not worth taking off a star and the increased vibrations gives it a deeper tone so I like it any ways. Great product!

Rated 3 out of 5 by from Good mount for hard driving, but with consequences. The mount does its job. Wheel and motor hop is pretty much gone, and the shifts definitely feel better during hard driving. However the first thing i noticed after installing the mount was the substantial increase in NVH, especially at idle with the AC compressor running. I honestly thought my mechanic had broken something, literally. During stop and go driving in traffic it is very noticeable. End of the day its all about compromise, while it has improved the performance, the NVH suffers. Kinda obvious, but i was not expecting it.

Rated 5 out of 5 by from Very good motor mount I installed this motor mount on 07/05/14. I also changed my front motor mount at the same time, different manufacture. The reason I chose this motor mount was because of its size when compared to other aftermarket rear motor mounts. Cobb also has a reputation for making quality products. I installed the rear motor mount for a specific purpose, it helps get rid of the banging and rocking of the motor on hard launches. Replacing the front motor mount was done for the same reason. After replacing both parts there is a lot of vibration in the car. I have put 200 miles on the parts and the vibration has gone down some. I cannot say what the vibration is with just the Cobb part as I have not driven the car with just the Cobb motor mount. Torque steer has also been reduced.

Rated 4 out of 5 by from Makes A Big Difference My Focus ST has/had the updated RMM, but this still makes a world of difference. I've had it on for about 3 weeks now and couldn't be happier. The NVH has settled a little since the first day, and is only really an issue now when idling AND the A/C on. Otherwise, great product. Wheel hop is down a lot and I'm able to put power down a lot better. 1st to 2nd gear change is smoother with no audible "clunk" as with the stock RMM. Overall, a good investment if you actually like to drive the ST for what it was made to do.

Rated 5 out of 5 by from Amazing Product Despite the manufacturing issue with the durameter sizing which was fixed, a phenomenal product. With the stock mount, there's extreme amounts of wheel hop, which is 70% gone when this mount is installed. The rest of the hop should be removed when the other two side mounts are installed, although they are unfortunately sold another site. Also, with the stock mount, torque steer is insanely high, although with the new'll be asking yourself what torque steer even is.

Rated 5 out of 5 by from Must have Prior to installation (stock engine) upon hard acceleration and shifting gears there was a noticeable "clunking" noise that was unnerving. The stock mount is inadequate and is made for comfort and not performance. The Cobb mount solved that problem and now we have solid shifts and the "clunking" noise is gone. However, we do have more engine vibration felt in the car. This is a small price to pay for such an amazing "Bang for the buck" Bolt on! I rate it as a MUST HAVE

Product Questions


So I finally got this installed on my 2014 st, and i noticed that it has vibration around 1000 rpm, and i saw that several other people have reported this. Is this something reported alot? And does driving on the RMM help a little bit with this? Thanks!

Asked by: Al3x
That's one of the tradeoffs of a stronger motor mount - you get more power to the wheels, but a bit more vibration.
