Harnessing up to 381PS and transferring it to the tarmac through the AMG Speedshift DCT 7-speed gearbox and the MFA front-wheel-drive biased 4MATIC system requires absolute driveline rigidity. Under aggressive race starts and hard corner exits, the factory rubber mounts can deflect, leading to axle tramp and a loss of momentum. While many high-horsepower track builds will eventually require stiffened Engine Mounts to handle massive torque spikes, establishing a solid foundation begins with upgrading your chassis mounts. Eliminate unwanted driveline movement and secure your setup by installing stiffened polyurethane Drivetrain Bushes to ensure every ounce of power reaches the road seamlessly.
