South Bend's Stage 3 Endurance Clutch Kit for the STI transmissions is based around a solid face clutch disc for optimal comfort and operation but features a stiffer pressure plate capable of holding 615 ft. lbs. of torque. The material used is a kevlar base and the material is segmented along the disc backing. Circuit racing is kept in mind for this kit due to its ability to transfer power at high energy levels. The kit comes complete with a pilot bearing, alignment tool, throwout bearing, pressure plate, and clutch disc.
