Spec Clutch ST632 Stage 2 Performance Clutch Kit - Pure Kevlar

The Spec Clutch ST632 Stage 2 Clutch Kit is engineered for drivers who demand more holding power than a stock clutch without sacrificing daily drivability. Ideal for mild to moderately modified naturally aspirated and power adder engines, this kit also excels as a long-lasting, street-friendly upgrade for stock power levels and spirited driving.

At the heart of the Stage 2 kit is a segmented or full-faced pure Kevlar disc with steel backing. This friction material delivers smooth, stock-like engagement characteristics while offering superior torque capacity and exceptional wear life compared to Stage 1. The hub is double-sprung with spring cover reliefs for added flexibility, and all hub components are heat-treated for long-term strength and durability.

Kit Includes:

• High-clamp performance pressure plate
• Pure Kevlar friction disc with steel backing (segmented or full-faced)
• High-torque double-sprung hub and disc assembly
• Release bearing and alignment tool kit (select applications)

Recommended Driving Applications:

• Street / Daily Driving
• Drag Racing
• Pulling
• Autocross

The SPEC Stage 2 clutch kit strikes the ideal balance between performance and everyday usability — significantly stronger than stock with virtually no compromise in pedal feel or shift quality.
