It is well known that the stock rear motor mount on the Focus ST is a weak link. Custom Performance Engineering, Inc. has chosen to think outside the box on this and come up with a completely new design. To do this, cp-e™ carefully studied the layout of the stock Focus ST rear motor mount. Immediately after removing the rear mount it was decided that a better design could be achieved.
The way the Ford Ecoboost engine mount system works is that the two side mounts provide a rotational mounting point and the bottom of the engine is free to swing like a pendulum if just these two mounts are installed without a lower engine mount. Now, if you take the stock engine mount and put it in place with its horizontally mounted bushing and you apply some power, it will help stop the engine from swinging but you are now stressing the bushing in two directions. These types of bushing are not really meant for this and they are unable to prevent the engine from forcing the mount to slam into the frame.
So cp-e™ came up with a way to stress the bushing in only one direction. By remaking both pieces of the rear engine mount cp-e™ was able to mount the bushing vertically so that the pendulum effect of the engine is stretching or pushing in only one direction. This also increases the durability of the engine mount substantially. Orienting the bushing in a way that allows it to be compressed properly has allowed us to create a mount that provides a stiffer system without using an overly stiff bushing.
cp-e™ goes a step further using EPDM, a sort of rubber bushing. Urethane begins to fail at temperatures as low as 200°F and generally the mounts need a higher durometer rated bushing in order for the bushing to hold together. Our rear motor mount is a perfect example of when not to use urethane. The mount bolts directly to the transmission, transferring a large amount of heat to the mount and the bushing. EPDM holds up to this heat, and doesn’t begin to break down and fail. EPDM also carries a higher density than urethane, so the bushing can have a lower durometer rating while keeping a high reliability. Why is that good? Higher durometer ratings provide more vibrations through the vehicle and to the cabin, raising the NVH (noise, vibration, & harshness) value within the cabin.
To create this mount two blocks of aluminum, starting at 17.1 lbs are slowly whittled down over the course of a couple of hours in our CNC machine to a final weight of 2.17 lbs. This process takes a lot of time but was necessary to give the benefits that this mount has to offer. Once the pieces are machined, the bushing is installed, and secured in place by the retaining ring. From here, the mount takes its final step to the cleaning and packaging department.
Through initial testing our mount has shown to eliminate the factory ‘bang’, and the included wheel hop while providing a low durometer bushing in order to keep the in cabin vibrations low. It is to be expected that vibrations will be added in some points of the driving experience, but this effect comes solely from stiffening up the engine mounting system.
Help control engine deflection and get more power to the ground with Steeda's Lower Engine Mount for your 2013-2018 Focus ST 2.0L or RS 2.3L.
Our upgraded engine mount is constructed from 6061 billet aluminum and comes with two sets of different bushings.
The red soft 70 durometer bushings will greatly increase control over the factory mount while keeping smooth engine/vehicle operation.
The black stiffer 88 durometer bushings will further increase control but introduce a mild level in vibration and harshness into the vehicle.
Our mount is an easy bolt on installation that will noticeably improve launching, power delivery, and shifting feel.

Note: Fits 2007-2013 Mazdaspeed 3 (Requires a longer bolt - Not included).
Upgrade your passenger side motor mount on your 2.0L Focus ST or 2.3L RS EcoBoost with our heavy duty passenger side motor mount and chassis bracket.
Steeda designed this motor mount for street and race use by providing two different bushing options. Our red bushings are softer and intended for street use with only minimal NVH increase, and the black bushings are harder and intended for race use. The race use bushings produce higher levels of NVH (noise, vibration, and harshness) and are therefore not recommended for street use.
We not only replace the mount itself but provide a much stronger chassis mount bracket as well. This motor mount will help improve launching by eliminating any deflection which could cause front wheel hop and comes with a lifetime warranty.

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.
FEATURES
Our mount is unique compared to our competitors mounts both in form and in function. We have incorporated a unique method of holding the mount in the vehicle. Features • Billet CNC construction • EPDM Bushing • CNC lathed aluminum bushing spacers • Stabilize the engine rotational movement • 60A or 75A durometer options • All necessary hardware included Instead of placing all of the force on the center bushing pin, the load is distributed throughout the bushing with the CNC lathed aluminum spacers. This load distribution increases the effective stiffness of the bushing under engine loads allowing a lower durometer bushing to provide more stiffness. cp-e™ goes a step further by using EPDM, a sort of rubber, bushing. Urethane begins to fail at temperatures as low as 200°F and generally the bushings need a higher durometer rating to hold together. The Focus rear motor mount is a perfect example of when not to use urethane. The location of the mount allows a large amount of heat to be transferred to the bushing. EPDM holds up to this heat, and doesn’t begin to break down and fail. EPDM has a higher density than urethane, so the bushing can have a lower durometer rating while keeping high reliability and support. Why is that good? Higher durometer ratings transfer vibrations through the vehicle and into the cabin, raising the NVH (noise, vibration, & harshness) value.
