Roll Restrictor [Mk8 Fiesta ST] 2.0 Duratec 6 ARP flywheel bolts (1The mountune roll restrictor for the Mk8 Fiesta ST 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. The EcoBoost engine found in the Fiesta ST generates a 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.
