Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

Stock rubber flex discs allow for a slight amount of give, especially under heavy acceleration and, depending on the amount of force applied, could potentially tear or split. This slight flex/give can prevent instantaneous transfer of force to the wheels, making accelerations unpredictable, or even lead to your vehicle being stuck on the side of the track. To combat this, IRP's Performance Flex Disc was developed. Made of CNC machined aluminum, this flex disc won't actually flex, and the polyurethane bushings will only provide a enough give to dampen some vibrations and prevent damaging the transmission. This is perfect for high torque applications such a drag cars and dedicated track cars that want immediate response and long term reliability.

78mm Diameter with fitment for M10 nuts/bolts.
