cp-e™ xFlex Stage 1 Ford Focus RS RMM Rear Motor Mount

Custom Performance Engineering is very proud to release the first aftermarket EPDM (ethylene propylenediene monomer) rubber engine mount for the Focus RS! CNC machined from a single piece of billet 6061-series aluminum; this mount is not only totally indestructible, but it also transmits far less NVH (noise, vibration and harshness) into the cabin than comparable mounts.

Focus RS RMM

Our Focus RS RMM 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.

Focus RS RMM Features

• Billet CNC construction
• EPDM Bushing
• CNC lathed aluminum bushing spacers
• Stabilize the engine rotational movement
• 65A or 70A 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.


EDPM Bushing

Unlike nearly all other engine mount manufacturers, we use EPDM for our bushings. This provides much more vibration resistance when compared to polyurethane. This material is also extremely resilient and is able to stretch and even develop small cracks without affecting its structural integrity. EPDM is much more expensive to produce, but it is a far superior bushing material.


Pressed Center Insert

Our metal inserts are physically pressed into our EPDM bushings. This allows the bushing material and the metal to have a perfect connection without any gap. Other manufacturers cut their material out to fit, leaving small tolerances where the metal can still vibrate. Our construction allows the EDPM to absorb the vibrations and allows the metal inserts to smoothly move with the EDPM.
