Competition Clutch Lightweight Steel Flywheel for K-Series Acura RSX, TSX & Civic Si (2-8090-ST)
Unlock quicker throttle response and seamless high-RPM acceleration across your tuned K-Series platform 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 hard street tuning, drag tracking, and road course competition.
Why Choose the Competition Clutch ST Flywheel?
- Optimized High-Rev Response: Engineered specifically to complement the high-winding power profiles of performance K-Series setups, dropping revs instantly for blazing fast shifts.
- Preserved Driveability: Specifically engineered for premium street-driven builds to retain smooth, reliable launch characteristics without excessive engine bogging or pedal chatter.
- 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.

Break-In Procedure
After you install your new Competition Clutch you will want to make sure that the clutch is properly broken in for ultimate operation. To break in your clutch, shift as often as possible during the first 500 miles, by doing so you will make sure that the material from the disc is embedded into the friction surfaces of the pressure plate and flywheel. Following the break-in procedure will ensure that your clutch has the longest possible lifespan. If you have any questions, please reach out to our tech department and we will be happy to help.
