Roll Restrictor

The mountune Focus roll restrictor 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 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.

Compatible with mk3 Focus RS, mk3 Focus ST pre & post facelift, mk3 Focus 1.6 EcoBoost mk2 Focus RS & RS500, and mk2 Focus ST.

Kit features:

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

    Roll restrictor

    Slightly more difficult to fit to the mk3 RS than the mk2 RS, but still really easy to fit you dont need to use the video but its nice that you can have a look before you do the job! The product itself is mountune so fit perfectly first time and simply transforms the way the car behaves. If you concentrate really hard with the car at idle with ac running yiu can feel a little more vibration but in return you get a smoother gear change and NO axle tramp/hop especially noticable when driving hard in the wet. I will say I'm no mountune fan boy but was really impressed with the roll restrictor

    Great bit of kit

    Easy to install and the gear changes are so much smoother. What NVH?! Hardly noticeable. Wish I’d done this ages ago. Teamed up with the short shift arm it changes the whole driving feel. You will not regret buying this!
