South Bend K70350F Clutch and Flywheel Kit Audi A4
The South Bend K70350F Clutch and Flywheel Kits are offered in a variety of configurations to suit your needs. For anything between a stock engine for daily driving up to stage 3 cars for the track, South Bend has you covered. These kits include a South Bend single mass steel flywheel. Single mass flywheels are lighter than the factory dual mass flywheel design which helps acceleration but does not dampen clutch noise.
South Bend K70350F Clutch and Flywheel Kit Vehicle Fitment:
- STAGE 2 DAILY - K70350F-HD-O - up to 315 Ft-Lbs:
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.
Recommended usage is daily, street and moderate race.
- STAGE 2 ENDURANCE - K70350F-HD-OFE - up to 450 Ft-Lbs:
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.
- STAGE 2 DRAG - K70350F-HD-DXD-B - up to 500 Ft-Lbs:
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.
Recommended uses are drag racing, drifting and limited street.
- STAGE 3 DAILY - K70350F-SS-O - up to 410 Ft-Lbs:
This clutch package is designed for high HP vehicles desiring a start performance similar to O.E. The pressure plate is race engineered and SFI approved with significant load increase over stage 1,2 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 which reduces wear and glazing.
Recommended usages are daily, spirited street and occasional track.
- STAGE 3 ENDURANCE - K70350F-SS-TZ - up to 445 Ft-Lbs:
This kit uses the same race engineered SFI approved pressure plate as stage 3 daily package. 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 3 DRAG - K70350F-SS-DXD-B - up to 530 Ft-Lbs:
This clutch package is built to handle heavily modified cars and designed to function according to the specific needs of the 1/4 and 1/8 mile track. The pressure plate for this kit is a SFI approved race cover engineered to disengage with less pedal travel thus 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, pulling, drifting.
