Maximize Your Evo XÍs Throttle Response and Track Performance

Unleash the full potential of your turbocharged 4B11T build with the Competition Clutch Ultra Lightweight Steel Flywheel (Part # 2-645-1STU). Engineered specifically for high-revving demands, forced induction setups, and aggressive track or rally racing, this 11.00lb flywheel is the ultimate upgrade for drivers who refuse to compromise on performance.

Why Choose the Competition Clutch STU Flywheel?

• Rapid Revving: Weighing in at just 11.00lbs and machined with significantly less material to drastically reduce rotational inertia, allowing your Evo to rev faster and build boost with less latency.
• Bulletproof Durability: CNC-machined from a single piece of premium 4140 forged steel. Unlike multi-piece aluminum flywheels, this one-piece design eliminates ring-gear separation and warp risks under extreme heat.
• Built for Power: Perfectly matched and highly recommended for Stage 3 and up clutch applications, built to hold the aggressive torque of tuned Evolution models.
• SFI Certified Safety: Formed from high-tensile materials to safely handle the high RPMs of competitive racing and high-horsepower boosted applications.

Whether you are shaving seconds off your lap times or building a high-horsepower forced induction street machine, this ultra-lightweight steel flywheel delivers the crisp shifts and lightning-fast acceleration your Lancer Evolution X deserves.
