Transferring up to 450 PS to the tarmac demands a rigid driveline, whether your 911 is equipped with the tactile 7-speed manual gearbox or the rapid 7-speed PDK dual-clutch transmission. The rear-mounted transaxle generates substantial pendulum forces during aggressive cornering, causing factory rubber mounts to deflect. Installing stiffened polyurethane Drivetrain Bushes secures the powertrain, sharpening throttle response and shifting precision. For dedicated motorsport applications, future driveline upgrades such as heavy-duty clutches, lightweight flywheels, and solid engine mounts are vital to ensure the chassis handles aggressive launch inputs without hesitation.
