The cause is the soft rubber that manufacturers use in their mounts to dissipate the driveline vibration. Softer rubber means you’ll feel less vibration from the engine and shifts. The downside is that softer rubber allows the engine and trans to twist more when torque changes.

Using our AWR’s engine mounts with urethane bushings will result in a more direct application of power to the wheels. The torque isn’t wasted twisting the engine, but goes more quickly to the wheels. You will feel a bit more vibration that the stock mounts had masked, but most people that like to drive hard, prefer AWR’s mounts to the stock. We recommend the 70 durometer bushings for street cars, which is stiffer than a stock mount but not too harsh. The 88 and 95 durometers are respectively harder and recommended for racing applications.
