Roll Restrictor [Mk6/7 Fiesta ST]

The mountune V2 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.

    Roll restrictor

    Bought this after reading that it can stop noisy gear changes that happen usually on 1st to 3rd ,because of the engine moving alot , didnt solve it but made it better ,what it has done is made everything feel tighter and stopped a bit of torque steer

    Best engine mount out there

    Fitting is pretty simple if you can get under the car, instructions online are very easy to follow. The results however are extraordinary the wheel hop is gone, the power delivered is instant on launch, couple with the short throw shifter you'll feel like driving a new car.

    Roll Restrictor Mk7 Fiesta ST - Mountune MP215

    Fantastic! Car currently has around 45,000kms and the stock Rear Motor Mount had done its time. Overall driveability is like stock if not better, Ironically less vibrations as well. However combined with the Short Shift Kit, engagement is better and wheel hop is gone. Shifts smoother as well. You will not lose Daily Driveability. To get the best results out of the Roll Restrictor (Rear Motor Mount) you should combine it with the Short Shift kit. Both are really easy to install with basic hand tools shouldn't take you more than 1.5 hours to do both if you have basic machincal and tool knowlage and will fundamentally change the way the car feels.
