The Competition Clutch ultra-lightweight steel flywheel for 1990–2005 Honda Civic D15/D16/D17 applications is a one-piece 4140 forged steel unit designed for naturally aspirated street use. It preserves low-end torque and driveability while reducing rotating mass compared with heavier stock flywheels, making it well suited to Stage 1 and Stage 2 clutch applications where a lighter flywheel improves engine response without extreme trade-offs in drivability.
