• Significantly increased clamping force over stock for high-torque engines
• Rigid hub design for maximum power transfer and durability
• Aggressive engagement suitable for track use and heavily modified vehicles
• Lightweight flywheel reduces rotational mass for improved engine response

Kit Includes:

• High-performance pressure plate with increased clamping force
• Stage 4 rigid hub clutch disc
• Lightweight flywheel (aluminum or chromoly construction)
• Release bearing
• Alignment tool
• All necessary hardware for installation

Application Specifications:

• Designed for 2018-2021 Subaru WRX with 2.0L DOHC FA20DIT turbocharged engine

This Stage 4 clutch kit is engineered for enthusiasts running increased boost, upgraded turbochargers, or other performance modifications that exceed the capacity of OEM or lower-stage clutches. The rigid hub design provides maximum durability but will have a harsher engagement than street-oriented clutches, making it best suited for dedicated performance applications.
