Spec Clutch ST881 Stage Performance Clutch Kit - 1 with Carbon Kevlar Disc

The SPEC ST881 Stage 1 Clutch Kit is a high-performance clutch system engineered for drivers who demand reliability and responsive engagement across a wide range of driving conditions. Built around a carbon Kevlar-based organic friction disc, this kit delivers smooth, predictable clutch engagement while significantly extending service life compared to standard OEM clutch components.

The friction disc features an integrally bonded steel backing that reinforces the lining under high clamp loads and elevated operating temperatures — keeping performance consistent whether you're commuting or pushing the car on a road course.
