Clutch selection can be difficult with all of the options available. Over the years we have tested a variety of clutches and to date the Clutch Masters variants have been the most reliable and user friendly. We offer 3 different options for the Kappa platform in the form of Clutch Masters Stage 4, Stage 5, and a twin disk Stage 6.5.
Stage 4 and Stage 5 both include a high torque heavy duty pressure plate. This pressure plate will have a stiffer pedal feel over stock, but provides the clamping force needed for additional torque. They both include a 6 puck ceramic disc; however, the difference between the two is that Stage 4 includes a sprung hub on the disc, and the Stage 5 is a solid disc. The Stage 5 will provide a racier feel and enable faster shifts at high RPM.
Both Stage 4 and Stage 5 can be used with either the stock dual mass flywheel or the Clutch Master's aluminum flywheel, found here.
The Stage 6.5 twin disk kit is an all out race only clutch for this application. We do not recommend it for a street car.
We have our full Pressure Plate, Clutch, and Flywheel Kit here.

ClutchMasters Stage 6.5 Clutch Kit (Twin Disc)
Clutch Masters is proud to introduce the finest and most economical multi-plate clutch systems available for today’s high performance vehicles, the 725 Series. Clutch Masters Twin Disc systems are pure racing technology that also works well in high performance street applications. They are designed to hold tremendous horsepower and torque ratings, while retaining a very smooth operation. By slightly increasing the clamping force of the pressure plate and adding to the square inches of usable disc area, CM Twin Discs significantly increase clamping values with only a 25-50% increase in pedal pressure depending on the application. The cover assembly is machined from billet aluminum with 25% more tensile strength than the competition’s cast unit. The flywheel is machined from billet 6061-T6 aluminum to meet SFI spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA and NASA. Each aluminum flywheel includes a replaceable heat shield. Steel flywheels are also available on select applications.
725 SERIES – (7.25” Twin Disc)
The 725 series is a smaller diameter assembly, which creates less rotating mass and offering quicker, and smoother shifting with much better throttle response.
