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

    So the stock one on the vehicle used to get a lot of hopping as you took off quickly, with the Mountune restrictor it doesn’t do it as much, I’m gonna need the differential to go with it which will happen, but first I’m gonna do the induction kit and exhaust system

    Focus RS MK 3 Roll Restrictor

    Well engineered, straight forward to fit except for that pesky 4th bolt. Can immediately feel a reduction in the engine roll even on startup everything feels tighter. Some how under acceleration the car feels more planted, I guess the feeling is analogous to strapping in a loose baby rhino versus it being free to roll about in the car.
