For those who require penetrating engagement and/or continue to break springs, the Competition Clutch Domestic Stage 5.5 0420 Four Puck Ceramic Rigid Clutch Kit is the direction you should consider. Similar to the 0620 six puck disc, but the 0420 is a rigid assembly without springs. This solid disc with ceramic buttons delivers a 120-250% increase in holding capacity and should be used only be the driver that requires instantaneous power. The solid high torque disc engages and disengages instantly. This should be considered a race only clutch and harsh engagement should be expected.
