USP Motorsports is pleased to present South Bend / DXD clutches for your Audi 4.2L V8. DXD clutches are developed and tested by DXD across many different friction products, pressure plate loads and flywheel designs with one goal in mind, to create clutch systems not only with perfect balance and symmetry but also to perfectly complement engine modifications without compromise in reliability, drivability or enjoyment.

The success of the development efforts has produced a performance clutch product line of the highest quality and performance available for Porsche, Audi and Volkswagen vehicles, DXD Racing clutches.

Each clutch system is specially matched to specific driving styles, uses and power levels to insure the needs of each client are accomplished. Often times, a compromise between drivability and pedal feel must be made to achieve power handling. If you are drag racing you will have different requirements for clutch operation than someone who wishes to participate in daily spirited driving or endurance racing. 

The Daily configuration is focused around an OEM pedal feel and initial engagement characteristics. This is the clutch that won’t give you a significantly stronger left leg but will provide many thousands of miles of ease of use and operation with the ability to transfer different Stages of engine performance to the tires. The quick engagement of most aftermarket clutches or the “grab” is greatly reduced and in most cases completely eliminated to allow for smooth clutch release and easy initial acceleration.

Flywheels manufactured by DXD are made from low carbon, hot rolled steel that is highly resistant to warping and perfectly suited for the friction materials mated to them. Single mount CNC machining guarantees precise tolerances and perfect balance exceeding O.E. specifications. Extensive field-testing has been done to determine the proper weight for each specific vehicle and to ensure smooth operation, safety and durability under extreme operating conditions.
