Roll Restrictor

The mountune roll restrictor for the mk6 and mk7 Fiesta ST reduces the amount of engine roll/movement during hard acceleration and gear changing.

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 roll restrictor is machined from high quality aluminum, and features a unique polyurethane front and large rear oval bushing – which helps with horizontal plane NVH.

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:

  • High quality anodised billet aluminum body
  • Polyurethane bushes
  • Reduction in engine movement 
  • Minimal effect on NVH

INSTALLATION NOTE: The main RR subframe bolt should be tightened to a torque value of 50Nm, while the three gearbox bolts should be tightened to 46Nm.

    The roll has been restricted

    Easy to fit and has made a big difference to how gear changes feel. Seems to put the power down in low gears a bit better too on an ST150.

    ST180 Roll Restrictor

    Quick delivery, quality product, easy to fit (about 30mins). Definitely makes difference to hear changes when engine under load, these torquey engines need a stronger bush. Not real noticeable NVH

    Amazing

    The car feels so much more solid during everything, not just spirited driving. I was worried about the NVH but after running it for the past week, I don't believe there's any extra. If you're on the fence get it, you won't regret it.
