Comp Clutch 2002-2005 Subaru WRX 13.47lb Steel Flywheel

Part Details:

The Competition Clutch forged lightweight steel flywheel is designed for naturally aspirated and street-driven applications where improved throttle response and drivability are the priority. It is compatible with both stock and performance clutch assemblies, making it a flexible option for a wide range of setups.

By reducing overall rotating mass while preserving low-end torque, this flywheel improves engine response without negatively impacting daily drivability. The lightweight design supports smoother acceleration and predictable engagement, particularly when paired with Stage 1 or Stage 2 clutch kits.

Manufactured from forged 4140 steel, the flywheel features a one-piece ring gear for increased durability. It is CNC machined and balanced to OEM specifications to ensure consistent operation, proper clutch engagement, and long-term reliability.
