The mountune Focus roll restrictor 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 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.
Bought these for my MK2 as they made such a difference plus the quality is also fantastic.
Just installed, does what it’s designed to do. No noticeable difference in NVH (possibly a minor increase in vibration right at idle - but so minor that I could be imagining it). Would definitely recommend it, reduces wheel hop and I reckon helps the shifts under full load. Keep up the good work
Very good and awesome product
