Audi a4 b8 clutch and flywheel kit

Southbend DXD Racing Clutch - Stage 3 'Drag' - Audi B8 A4 2.0T Quattro Clutch and Flywheel  Kit

Race Engineered Pressure Plates (SS)

These performance clutches deliver more transmittable torque and stability, longer life and superior thermal resistance. They also deliver noticeably better dynamics through higher clamp load when driving the vehicle to its limits.

Which clutch is right for me?

Stage III Daily

This clutch package is designed for high HP vehicles desiring a start performance similar to O.E. The pressure plate is Race Engineered (SS) and SFI approved with significant load increase over stage 1 or 2 pressure plates (+600-800 lbs.). Expect a pedal effort increase of 20%-25%. Discs are assembled with heat-treated wear resistant hubs; drive plates and springs for high load transfer and dependable operation. The sprung centers on the disc, in conjunction with the marcel fin between the linings, create a dual dampening effect that simulates O.E. start performance. A Performance Organic friction material with a high metal content increases torque and RPM capability and maintains low operating temperatures reducing wear and glazing. Recommended usages are daily, spirited street and occasional track.

Stage III Endurance

This kit uses the same Race Engineered SFI approved pressure plate as the Stage 3 Daily upgrade. The disc is designed for the special needs of a vehicle with circuit racing in mind. Kevlar friction material is used for its unique static to dynamic ratios of friction co-efficients at high energy levels. This translates to a perfect transition from one gear to the next. Discs are assembled with only performance components and equipped with torsion springs functioning as a damper between engine and gearbox. Recommend usages are Rally, Endurance Race, Clubsport, Autocross, Street and Daily.

Stage III Drag

This clutch package is built to handle heavily modified cars and designed to function according to the specific needs of the ¼ and 1/8th mile track. The pressure plate for this kit is SFI approved Race Cover engineered to disengage with less pedal travel shortening the shift time. Discs are a puck design, which reduces rotational mass and are assembled with all high carbon component pieces for maximum strength. The friction material used is Graphite impregnated Ceramic perfectly suited for drag racing because of its maximum friction co-efficient, rapid heat dissipation and abrupt engagement characteristics. Recommended uses are Drag, Towing and Drifting.

Flywheel Features

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.

Some Flywheels are a hybrid aluminum/steel combination flywheel .

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. SFI Approved!

Fitments / specifications:

• 2009-2013 Audi A4 [B8 - Chassis] 2.0T Quattro 6-Speed
• Torque capacity - 600 ft-lb
• *Please note, single mass flywheel units can cause some slight noise at idle, this is normal and does not harm anything. SFI Approved!

Tech Note : This Southbend Clutch Kit includes Southbend single mass flywheel PT#SBCF70614

Product Information

Stage 2 Daily

Engineered for HP modifications. 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.

Holds 375TQ

Recommended usage is daily, street and moderate race.

Stage 2 Endurance

This clutch system is designed for the racing climate. The pressure plate is precision balance 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.

Holds 440TQ

Recommended uses are daily and street with an emphasis on Rally and Endurance racing. 

Stage 2 Drag

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, heat transfer and torque capacity.

Holds 550TQ

Recommended use: Drag racing with limited street use.

All Stage 2 kits use the O.E. flywheel.
