The PFF76-920 Torque Mount Bushing Insert is an affordable and easy-to-fit bushing insert made from our yellow 70A durometer vibration-absorbing material, stiffening the OEM torque mount. This reduces twist of the engine under acceleration and during gear changes, giving the pedals a more direct feel and reducing wheel-hop, letting you get the power down that little bit quicker. For milder applications PFF76-920 can be fitted on it’s own, but will perform most effectively when fitted with our other Yaris GR powertrain inserts (PFF76-923 & PFF76-925) as a full set. There will be a minor increase in NVH when stiffening the powertrain mountings.
