South Bend DXD Racing Clutch Kit - Audi / B8 / S4 / S5 | K70619-HD-O

UroTuning is pleased to present South Bend / DXD clutches for your B8 Audi S4/S5 3.0T. 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.

Each DXD Racing clutch is offered in either a Daily, Endurance or Drag configuration to accomplish the power handling needed for your car.

NOTE: Photos used for reference only! Actual product may vary. *Only STAGE 3 clutch kits come with DXD Racing flywheel.

Stage II

The DXD Racing Stage 2 Clutch Upgrade is perfect for those who modified their engines to Stage 2 and Stage 2+ power levels. Offered in specific configurations of Daily, Endurance or Drag, the DXD Stage 2 is perfectly matched to your driving style and your specific use. Each Stage 2 Clutch is engineered to specifically support engine modification with increased clamp load and different material choices across the individual Stage 2 configurations. Each configuration includes all of the benefits of a DXD Racing Stage 1 Clutch Upgrade but also includes additional benefits specific to each.

This Heavy Duty Pressure Plate has an increased clamp load with little or no increase in pedal pressure. The Organic disc material has a high metal content that increases the co-efficient of friction by two times over a stock lining and increases rotational strength up to a 12,000 RPM burst point. This clutch system maintains a stock feel while offering strength and durability. Recommended usage is daily, street and moderate race.

This clutch system is designed for the racing climate. The pressure plate is precision balanced for vibration free operation at high RPM. The pressure plate fulcrum is altered for a positive disengagement and a quick shift. The disc is engineered with a Dual Damped design to provide accurate control when accelerating through corners. The friction material is a hybrid using a full face Feramic (Sintered Iron) lining on the flywheel side and a high metal content Organic lining on the pressure plate side. Engagement is positive yet buffered due to the high graphite content unique to Feramic facings. Recommended uses are daily and street with an emphasis on Rally and Endurance racing.

An SFI approved single mass flywheel is recommended for this application to get optimal performance.

This system features a Heavy Duty Pressure Plate modified for a puck style disc with no cushion between the linings to keep the clutch pedal travel short and quick. The puck design disc reduces rotational mass and total drive surface area while increasing pounds per square inch on the surface of the friction material. This combination minimizes inertia, accelerating the transfer of torque from the engine to the wheels. The friction material used for this race application is Graphite Impregnated Ceramic. This compound exceeded all other friction materials when testing for durability, reduced chatter, reduced heat transfer and an increase in torque capacity. Recommended uses are drag racing, drifting and limited street.
