Stage 3+ is the flagship stage for a high powered street or race car that requires a manageable and friendly engagement. The SPEC Stage 3+ features a carbon semi-metallic full faced material that offers unparalleled life, friction coefficient and drivability characteristics in one single package. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Suggested for very highly modified, streetable autocross & track driven WRXs.

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.
