Unleash Instant Throttle Response & Rapid Revs in Your 2ZZ-GE

Supercharge your powertrain's acceleration with the Competition Clutch Ultra Lightweight Steel Flywheel (Part # 2-617-1STU). Weighing in at a highly agile 10 lbs, this premium component sheds massive amounts of rotational mass compared to heavy factory equipment, unlocking the snappy, free-revving throttle response and quick RPM climb required for competitive track, rally, and performance street driving.

Why Upgrade to the Competition Clutch STU Flywheel?

• Track and Racing Ready: Engineered explicitly for forced induction setups (turbo/supercharged), circuit racing, and time attack builds. Well-suited for high-clamp Stage 3 and up clutch kits.
• Premium 4140 Forged Steel: CNC-machined from a single solid piece of chromoly steel. This rigid construction entirely eliminates the threat of ring-gear separation and friction-plate warping under extreme track heatãcommon issues found in multi-piece aluminum variants.
• Reduced Rotational Inertia: Formed with strategically less material on the outer diameter to dramatically reduce powertrain inertia, allowing your engine to snap right into its lift powerband during aggressive upshifts and heel-toe downshifts.
• SFI Certified Safety: Manufactured to rigid tolerances and certified to safely handle extreme racing RPM shifts without breaking a sweat.

Whether you're pushing a high-revving Lotus on the track or building a quick-shifting Celica street machine, this ultra-lightweight steel flywheel ensures your 6-speed platform transfers power instantly when you drop the hammer.
