Transmitting over 425bhp and massive twin-turbo torque through the rear wheels of your M3 via either the traditional 6-speed manual or the lightning-fast 7-speed DCT gearbox demands incredibly robust drivetrain hardware. Manual owners pushing beyond factory power levels will benefit immensely from Uprated Clutches & Flywheels engineered to hold substantial torque without slipping. While the F80 comes equipped with an Active M Differential, maintaining and upgrading your traction components ensures maximum corner-exit speed with our specialized Differentials (Limited-Slip) replacement hardware. Eliminate rear subframe flex and axle movement under hard launches with stiffened polyurethane Drivetrain Bushes, supported by our complete range of Misc Drivetrain Parts.
