The SPEC Stage 3 clutch kit features a carbon semi-metallic 6-puck sprung hub disc that has been the leading pucked clutch in drivability, life & torque capacity. Stage 3 is designed for street & race cars that require an aggressive but streetable engagement & high torque capacity. The hub is double sprung with spring cover relieves for flexibility & heat treated for strength and durability. Suggested for highly modified, street, autocross & track driven WRX. Special Notes: Torque capacity: 485ft/lbs Carbon semi-metallic friction material
JNA Performance does not recommend anything above Spec's Stage 3+ unless your car has improved driveline and transmission components and is a dedicated drag car (no street driving, etc.). Stage 4 and 5 clutch kits are unsprung making them noisy and harsh and unsuitable for street use.
