Transferring up to 317 lb-ft of torque to the rear wheels demands a rigid driveline, regardless of whether you operate the manual gearbox or the PDK transmission. Over time, factory rubber mounts deteriorate, causing unwanted powertrain deflection and imprecise gear selection. Installing stiffened polyurethane Drivetrain Bushes secures the transaxle and improves throttle response. For those developing dedicated track vehicles, future driveline modifications such as heavy-duty clutches, lightweight flywheels, and solid engine mounts are vital to ensure the chassis handles aggressive inputs without hesitation.
