Comp Clutch 04-20 Subaru STi Stage 3 – Segmented Ceramic Clutch Kit

Part Details:

The Competition Clutch Stage 3 – Street-Strip Series 2300 Clutch Kit is designed for street and strip builds that need significantly more holding power than stock, while maintaining controlled drivability. This assembly is rated for up to a 150% increase in torque capacity and delivers quick yet smooth engagement with extended service life.

The 2300 Series uses segmented Carbon Kevlar friction material paired with a performance pressure plate to provide strong bite, excellent heat resistance, and consistent performance in aggressive driving conditions.

Pressure Plate & Disc Design

The high-torque sprung disc features segmented Carbon Kevlar facings engineered to handle elevated temperatures and repeated high-load engagement. Compared to traditional organic materials, Carbon Kevlar offers improved durability and resistance to fade under demanding use.

A sprung hub design helps absorb drivetrain shock during engagement, improving drivability and reducing stress on transmission components compared to rigid race-style discs.

Street & Strip Engagement Characteristics

Engagement is faster and more direct than Stage 2 setups, while remaining smoother and more manageable than ceramic-based strip-focused clutches. This makes the 2300 Series a strong option for aggressive street driving, high-power street builds, and occasional drag use.

A 500-mile break-in period is required to properly seat the friction material and ensure optimal performance and longevity.
