Competition Clutch Lightweight Steel Flywheel for 1986-1993 Toyota Supra Turbo (2-717-ST)

Unlock quicker throttle response and faster boost response in your MK3 Supra Turbo without sacrificing daily driveability. The Competition Clutch Lightweight Steel Flywheel (ST suffix) is the ultimate upgrade for enthusiast drivers who want a more responsive engine while preserving critical low-end torque.

Engineered from premium 4140 forged steel, this one-piece design eliminates the risk of ring-gear separation common in multi-piece alternatives. It provides the perfect balance of weight reduction and thermal capacity, making it an excellent choice for vintage street builds, highway pulling, and track use.

Why Choose the Competition Clutch ST Flywheel?

• Optimized Throttle Response: Lighter mass helps reduce rotational inertia, allowing the heavy inline-6 turbo engine to spin up quicker and get into boost faster.
• Preserved Driveability: Specifically engineered for street-driven performance applications to retain smooth launch characteristics without excessive engine bogging.
• Perfect Clutch Compatibility: Perfectly matched and well-suited for Gravity, Stage 1, and Stage 2 clutch kits.
• One-Piece Forged Strength: CNC-machined from ultra-durable 4140 chromoly steel for maximum safety, reliability, and longevity under high-RPM abuse.
