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 designs can rattle your teeth out at idle or during throttle input. The COBB RMM utilizes unique voids custom molded into the 85A durometer bushing to absorb vibrations, but still reduce engine movement to aid getting all the power to the ground. The beautifully machined 6061 billet aluminum mount with zinc hardware will make you sad you have to hide it under your car.


The COBB Rear Motor Mount incorporates a unique bushing design engineered to improve traction and remove wheel hop without harshness.

Ford / Mazda Rear Motor Mount Focus ST 2013-2018, Focus RS 2016-2018, Mazdaspeed3 2007-2013 is rated 4.8 out of 5 by 94.
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 Feels like a whole new car. Finally the way I want it! Have had this on for about 3 weeks now and every time I drive the MS3 it feels like a new car from what I remember. Rumbles a bit more, but just enough. Feels much more connected to the ground. Torque steer 80% reduced. Wheel hop 70% reduced. I really enjoy driving the MS3 again now (to put this in perspective, the MS3 was my backup car for my 911. I just sold the 911 and told my wife I was going to put a few upgrades in the MS3. Sure I miss the 911 some, but have really been enjoying the MS3 with this upgrade much more than I thought I would). HIGHLY recommend this upgrade for anyone with a MS3. Slightly rumblier, but totally driveable like that.

Rated 5 out of 5 by from Noticeable difference! Probably took me about 30min to install - most of that time was spent trying to get the transmission bracket bolts to budge ... whoa! The COBB mount went in much faster once the transmission bracket was out of the way. If you don't have ramps already for your MPS, double check they'll fit! I bought some ramps but because the front skirting is so low, I couldn't actually drive up them. And as everyone else has noted, you do feel more vibration at idle but that's the trade-off I guess. I'm happy with the overall change in the 'feel' of my 2006 MPS.

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 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 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

Rated 5 out of 5 by from Quality part I was told after buying my car that the stock RMM in the 2013-14 ST was not the greatest. After doing some research, I finally bought my COBB RMM and installed it 3 days ago. This removal of the stock one was super easy. When I got to installing the new one, I had a hard time accessing some of the spaces to put the bolts back in but other than that it was super easy. I started my car up and definitely felt the vibration of the engine but I was told to give it some time and that would get a little better. As for the wheel hop... there is NONE! It took care of my problem in first and second gear where my car would jump like crazy. Everything feels a lot stiffer now too.

Rated 5 out of 5 by from Fantastic motor mount Well all I can say is WOOWW!!!! I bought this RMM for my 2013 MS3 and what a difference. I've been a manual tranny guy my hole life but for some reason when I bought the MS3 I could never make a smooth shift in the car. I put this thing on and 10 minutes later I was blown away with how smooth the shifts were. Totally worth your money. Also traction was improved dramatically.
