Competition Clutch Steel Flywheel for Naturally Aspirated Engines Lightweight...

Competition Clutch Steel Flywheel — Lightweight for Naturally Aspirated Engines Competition Clutch lightweight steel flywheels (ST series) are engineered for naturally aspirated and street-driven cars that demand immediate throttle response without sacrificing daily drivability. Ideal for Stage 1 and Stage 2 clutch setups, these flywheels preserve low-end torque while improving engine responsiveness and shift feel. Key Features Material: CNC-machined 4140 forged steel for high strength and durability. One-piece design: Eliminates failure points of multi-piece constructions for reliable performance. Optimized mass: Available weights from approximately 8 lb to 18 lb (application dependent) to balance acceleration and drivability. Street-friendly: Tuned to maintain smooth idle and low-speed torque for everyday use. Compatibility: Designed for naturally aspirated engines; not all applications offer both ST and STU variants—check fitment. Benefits Reduce rotational mass to gain crisper throttle response, faster revving, and improved clutch engagement while keeping power delivery usable for street driving. The durable 4140 steel construction ensures long service life under spirited use. Note: Verify the correct ST/STU availability and flywheel weight for your specific vehicle application before ordering.
