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.
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.Installation:
Going from the Vudu Rear Engine Mount to the Mountune Roll Restrictor was-forgive the cliche-like night and day. I noticed the difference immediately without needing any time to embed. Very impressed.
