Roll Restrictor

99
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 Powerflex 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
  • Powerflex 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.

Excellent quality as always

Great quality product instantly notice the difference in gear change. Personally I don’t notice any extra vibration. Very easy to install, hardest part is converting the OE mounting bracket from a hex to a circle to allow the roll restrictor to fit flush! Personally i removed the whole OE and bracket and used a hammer to remove the bracket. Then i filed the bracket to fit. Once installed and torqued it looks great and really improves on the drive-ability

Good quality

Easy to fit, slightly more vibration through the steering wheel on tick over but non through the gear lever that I can feel, I have not had chance to drive the car properly yet but reading other comments it seems like a worthwhile upgrade to improve the car. Mountune were great to deal with and the part was delivered a day after ordering.
