Harnessing 306bhp and transferring it through the AMG Speedshift DCT 7-speed transmission and MFA2 4MATIC all-wheel-drive setup requires absolute driveline stability. Under hard launches and aggressive corner exits, factory rubber mounts can flex and cause unwanted engine pitch. Stiffening your mounting locations with polyurethane Drivetrain Bushes locks down the chassis assembly. While dedicated high-power track builds may eventually seek upgraded Clutches, lightweight Flywheels, and stiffened Engine Mounts to handle extreme torque loads, establishing a rigid setup with uprated bushes is the essential first step to ensuring immediate power transfer to the road.
