Roll Restrictor [Mk8 Fiesta ST]
The mountuneĀ roll restrictor for theĀ Mk8 Fiesta STĀ reduces the amount of engine roll/movement during hard acceleration and gear-changes, whilst maintaining an acceptable level of NVH (Noise, Vibration and Harshness) for everyday use.
TheĀ EcoBoost engine found in the Fiesta ST generates aĀ considerable amount of NVH due to its 3-cylinder architecture, and as such, the OE roll restrictor has had to be designed in a way to minimise this harshness. Unfortunately, this also means the engine movement is considerable and this translates as unwanted wheel hop /Ā tramping -Ā which is unpleasant and detrimental to your car's overall performance.
Engineering an uprated mount to minimise this unwanted and performance-robbing characteristic, without filling the cabin with harsh vibrations, has been a challenge.Ā But using our decades of high-level engineering knowledge, and previous roll restrictor experience, has enabled us to produce what we believe to be the ultimateĀ balance for those wanting all of the performance benefits, without the unbearable vibration that the majority of other mounts exhibit - you'll still feel it, but not as harshly.
Machined from T-6061 billet aluminium, the mountune roll restrictor features unique mixed shore-hardness polyurethane bushes to counteract unwanted NVH and minimise vibration as much as possible, whilst still providing the required restriction in engine movement to enhance performance.
Features:
- High quality anodised billet aluminium body
- Bespoke mixed shore-hardness polyurethane bushes
- Reduction in engine movementĀ
- Prevents wheel hop
- Minimal effect on NVH possible
Due to the additional NVH created when the VDE (cylinder de-activation) strategy is enabled, for all users already in our SMARTflash ecosystem, you can also claim a free cylinder de-activation version of your m225 / m235 / m260 (Fiesta) calibration - justĀ specify your vehicleĀ VIN in the notes section when checking out.Ā and if the email used to make this purchase is different to the one used for your originalĀ SMARTflash purchase, please also supply that to ensure the industrialised calibration to support your vehicle is created and sent to you correctly.
Please note: AĀ compromise has to be made, and someĀ vibration at cold start and idleĀ may be more noticeableĀ on some vehicles.
Recommended torque settings: Subframe: 50Nm | Gearbox side: 45Nm.
