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 Focus Mk3 RS

    Had this fitted 4 months ago so had a good chance to feel what the difference would be. This Roll Restrictor has made a great change to how the car feels and handles. Feels a lot more stable and planted when accelerating. Haven't noticed any significant change or increase in vibration, so all good there. A worthwhile change and an excellent manufactured product.

    Good upgrade...

    Quality part..smoother gear change and less wheel hop. Expected the slight vibration on start up and when idling but is getting less and less ,or I'm just getting used to it ...

    Roll restrictor

    Purchased a couple of months ago now & only just got around to fitting it. Jobs relatively easy, hardest part was getting the car up in the air. Makes a noticeable difference in getting the power down and not losing traction, torque steer is no where near as bad. There is a slight vibration at lower rev’s . I’m really fussy over things like that and it won’t bother me at all. Definitely worth the money, should’ve fitted it earlier . Logo still point’s down on the new design
