These kits are complete with everything needed to install. All bolts, release bearing & alignment tool come with the clutch kit. Also, every kit comes with a lightweight steel flywheel. BSH uses Southbend Clutches in ALL of our VW/Audi project cars! Notes:When selecting the style of clutch from the drop down menus above use these tips to select the right clutch.  STAGE 2 DAILY:”Daily” signifies smooth engagement as being a key design elementEngineered 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:”Endurance” signifies the ability to withstand the stress and heat of road racing when used within the the output range.An SFI approved single mass flywheel is recommended for this application to get optimal performance. 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. Recommended uses are daily and street with an emphasis on Rally and Endurance racing. STAGE 2 DRAG:”Drag” signifies extremely aggressive engagement and pressure plate feel and while although can be used on a daily driver it is recommended against when comfort is a concern.Drag racing requires a Single Mass SFI approved Flywheel to be included with each kit when the original design is Dual Mass. 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.
