Revo RV581M500300 | MQB Lower Torque Mount Urethane Replacement Bushing

Arguably the most vital engine mount upgrade to consider, testing highlighted that the engines stock lower torque mount allowed a substantial amount of engine movement to occur. Although some improvements were noted during testing of an insert style upgrade designed to stiffen the standard mount, there was a significant increase in NVH felt in the cabin. This was dramatically reduced when completely replaced with the Revo polyurethane torque mount and also improved acceleration.

FITTING KIT

A Revo installation tool (sold separately) makes removal of the OEM mount and installation of the replacement as quick and easy as possible. This allows the OEM part to be removed and the Revo part to be installed without removing the sub-frame, reducing installation time and the need for axle re-alignment.

To achieve the optimal balance between performance and comfort, several different durometer bushings were tested on a Volkswagen Golf Mk7 GTI. Bushings were systematically tested at precise increments at each mount location. A 3-axis accelerometer was used to quantify the NVH levels being transmitted into the cabin, as well as the acceleration of the drivetrain during loading.

Accelerometer data gave us a way to compare mount combinations against each other with a low data error percentage and to quantify driver comfort as well as engine movement. Supplemental data was taken from VCDS to ensure each individual test was standardized over a given throttle, RPM and speed range. The graph shows the amount of vibration measured whilst driving through the gears.
