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
