mountune Roll Restrictor / Rear Motor Mount - Focus ST

2363-RR-AA

The mountune roll-restrictor / RMM reduces the amount of engine roll/movement during hard acceleration and gear changing. With a product such as this, care must be taken with the design and choice of materials, as a poor design can destroy the feel and driving experience of the car. With an extensive background working in the OEM market, mountune have the knowledge and engineering expertise to create a product which can reduce the engine movement by the desired amount, but with minimal effect to the NVH (Noise Vibration Harshness) level.

The mountune roll restrictor is machined from high quality aluminum, and features a unique size and shore hardness polyurethane bushing engineered to control with horizontal plane NVH. The bonus of using polyurethane is that not only has it been engineered to give increased stiffness without causing excessive vibrations, it also doesn’t deteriorate like rubber does, so the service life of the component is greatly increased.

  • High quality anodized billet aluminum body
  • Polyurethane bushing
  • Reduction in engine movement
  • Minimal effect on NVH

Nice upgrade over stock August 17, 2017
Reviewer: John from Detroit, MI United States  
Fits and does exactly as it's supposed to.  Installed and breaking in as we speak.

Roll Restrictor OMG! Huge difference August 7, 2017
Reviewer: Kurt Smith from Henderson, NV United States  
Before the rear engine mount you could feel the engine shift and when you braked hard the car felt like it might fish tail.

After the install , the car now moves as one unit. No need for sway bars, it's that much of a difference.

Mountune Rear Motor Mount August 6, 2017
Reviewer: Anonymous Person from Albuquerque, NM United States  
Lots of confusing and mixed reviews of other brand RMM on the market, which lead you to focus on durometer ratings of that particular mount. Durometer rating should be taken into account along with the overall design of the mount. I believe Mountune got it right. Perfect balance of stiffness without turning your vehicle into a rattle trap. Decreased wheel hop dramatically, along with decreased engine movement. Shifting is much smoother due to less overall movement and only feel a small increase in vibration, which to me feels perfect for the car. Exhaust feels a bit more noticeable.  Installation is straightforward with the correct tools. Excellent product, and extremely satisfied!

A year strong, no hop August 5, 2017
Reviewer: Trevor Brown from Corona, CA United States  
After a year of hard launches and Autocross, this motor mount has held up with no signs of wear. Initial break-in was stiff, but after only a couple hundred miles everything smoothed out. NVH is very minimal, at most felt in the pedals at idle. Worthy investment, as my prior CFM failed within a few months.

RMM Stage 3 2016 Focus ST August 3, 2017
Reviewer: Jeff Spencer from CONCORD, NC United States  
Well worth the price.  This mount reduced torque steer, made for smoother shifting, smoother power delivery and made the car feel much more stable at high speeds on twisty back roads.  Can't believe I waited this long to upgrade the RMM.

I already had the FSWerks lower front stress bar installed on my car, so I didn't really notice any added NVH other than a little at idle with the a/c on.  Even that is barely even noticeable.   Highly recommend this mount.
