Roll Restrictor [Mk2 / Mk3 Focus RS/ST]

The mountune Focus roll restrictor for Mk2 and Mk3 Focus ST & RS reduces the amount of engine roll / movement during hard acceleration and gear changing, plus helps reduce 'wheel-hop', particularly when the power output has been increased.

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 Focus RS/ST roll restrictor is machined from high quality HE30 aluminium, and features a unique size and shore hardness polyurethane bush.

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.

Kit features:

  • Engineered and optimised for Focus RS
  • High quality HE30 anodised billet aluminum body
  • Bespoke size and shore hardness polyurethane bushes
  • Reduction in engine movement 
  • Minimal effect on NVH

    Roll Restrictor

    Superb item as you would expect from Mountune. Quick delivery and excellent service. The car has some vibration on idle and more noticeable with the AC on. The car just feels tighter now the engine is not moving about. Used in conjunction with the Billet Short Shifter gives a great driving experience. Wish I had done the upgrade sooner.

    Exactly as expected

    Background I’m not a mechanic nor pretend to know much about cars. I have a basic knowledge of tools etc. Fitting Even for someone of my background the fitting of this wasn’t to hard, following a YouTube video was able to remove my old mount and fit the new one with not much of an issue. Needed some WD40 to slide the mount into place and few of the bolts from the previous mount where bent so made removing them a bit harder. All in all the hardest part was jacking and lowering the car/finding good spots for axel stands, ended up using the part of chassis that connects to the wheels. Performance Straight off the back on my first drive I noticed a massive improvement on “Wheel hop” the car just sits to the ground and when you put your foot down the car pushes down onto the road rather than bouncing along it. Many people have stated about the vibrations and yes sitting at idle with the air con on it does rattle a bit, however without aircon the difference is barely noticeable, if anything the feedback via the steering wheel makes you feel like your actually driving the ST rather than guiding it. Overal Very happy with the purchase would be 5* if it wasn’t for the air con vibrations, hopefully it wears in as others have said it did and I can update my review accordingly to 5*
