Maximize Your K-Series Engine's Throttle Response and Track Performance

Unleash the full potential of your high-revving Honda build with the Competition Clutch Ultra Lightweight Steel Flywheel (Part # 2-800-STU). Engineered specifically for the demanding powerbands of K20 powerplants, forced induction setups, and aggressive track, autocross, or time-attack racing, this 11.00lb flywheel is the ultimate performance upgrade.

Why Choose the Competition Clutch STU Flywheel?

• Rapid Revving: Weighing in at 11.00lbs to drastically reduce rotational inertia, allowing your K-Series engine to rev faster, climb the tachometer instantly, and drop straight into the VTEC zone.
• Bulletproof Durability: CNC-machined from a single piece of premium 4140 forged steel. Unlike multi-piece aluminum flywheels, this one-piece design integrates the ring gear directly, eliminating separation and warp risks under extreme clutch temperatures.
• Built for Power: Perfectly matched and highly recommended for Stage 3 and up clutch applications, built to hold the aggressive engagement of racing clutches.
• SFI Certified Safety: Meets and exceeds strict specifications to safely manage high RPMs and the extreme centrifugal forces of competitive motorsport racing.

Whether you are shaving seconds off your road course lap times in an RSX Type-S, building an all-motor street machine, or dialing in a high-horsepower turbo Civic build, this ultra-lightweight steel flywheel delivers the crisp shifts and lightning-fast acceleration your Honda deserves.
