Dual dampeningeffect 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:

Recommended for single mass flywheel (SMF) when original design is DMF to achieve optimal performance. 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:

Drag racing requires a Single Mass Steel Flywheel to be included with each kit when the original design is Dual Mass Flywheel. This clutch package is built to handle heavily modified cars and designed to function according to the specific needs of the ¼ and 1/8^th 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, pulling, drifting.  

STAGE 4 EXTREME:

This is a build to order clutch kit intended for cars with HP modifications exceeding the stage 3 parameters. The Race Engineered pressure plate is modified for maximum plate load. The discs are puck design with sprung and un-sprung options.  Friction material options include Sintered Iron and Graphite Impregnated Ceramic.  Engagement characteristics can be abrupt.  Hydraulic systems may need enhancing for proper clutch separation.  Single mass steel SFI approved flywheels are required for safety. Torque ratings are calculated at time of ordering. 

Race Engineered Pressure Plates (SS) used in Stage 3 and 4 clutch kits:

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.

Flywheel Features 

Flywheels manufactured by SBC 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.
