Under hard acceleration, your entire engine and transmission actually rotates due to compliance in the factory bushings.  While the soft factory bushings do a good job of damping engine vibration, they can also create a rubbery, vague response in the vehicle's powertrain. 

Our torque arm insert works in concert with the OE rubber bushing.  With the insert installed, you car's throttle response will feel better and your shifts will feel more crisp and defined, especially on manual transmission cars.

Audi and VW have changed the torque arm mount mid-production cycle.  To ensure you receive the correct item, please make sure that your OE mount looks like the mount in the second picture above.  If it does not, use part number 22.10.91

Please note that polyurethane is not as compliant as rubber.  As a result, you may notice a slight increase in ride harshess and engine vibration after installation.
