• High-clamp pressure plate for increased clamping force over stock
• Carbon semi-metallic 4 or 6 puck friction disc — 6 puck is standard on most applications; 4 puck available by specification at time of ordering
• High-torque sprung hub disc assembly — double sprung with spring cover reliefs for flexibility and heat-treated components for strength and long-term durability
• Bearing and tool kit included for a complete installation package

The Stage 3 sits within SPEC's street/strip range (Stages 1–3+) and is ideal for high-performance builds that see both everyday use and track duty. The carbon semi-metallic puck disc design delivers proven performance in drivability, service life, and torque capacity. Prior to installation, the existing flywheel must be resurfaced unless a new SPEC flywheel is being used. A minimum 450-mile break-in period is required before full-throttle engagement or launch-style use.
