Maximize Your RotaryÍs Throttle Response and Track Performance
Unleash the full potential of your high-revving 13B rotary engine with the Competition Clutch Ultra Lightweight Steel Flywheel (Part # 2-745-STU). Engineered specifically for high-RPM demands, forced induction setups, and aggressive track, drift, or rally racing, this 9.68lb flywheel is the ultimate performance upgrade for drivers who refuse to compromise.
Why Choose the Competition Clutch STU Flywheel?
- Rapid Revving: Weighing in at an ultra-light 9.68lbs to drastically reduce rotational inertia, allowing your rotary engine to rev faster, reduce lag, and climb the tachometer instantly.
- Bulletproof Durability: CNC-machined from a single piece of premium 4140 forged steel. Unlike multi-piece aluminum flywheels, this one-piece design integrates the ring gear directly, eliminating separation and warp risks under extreme track temperatures.
- Built for Power: Perfectly matched and highly recommended for Stage 3 and up clutch applications, handling increased horsepower and high-boost applications with ease.
- SFI Certified Safety: Formed from high-tensile materials to safely manage high-RPM rotary abuse and the extreme centrifugal forces of competitive motorsport racing.
Whether you are shaving seconds off your road course lap times in an FD RX-7, setting up a drift build, or maximizing your RX-8, this ultra-lightweight steel flywheel delivers the crisp shifts and lightning-fast acceleration your rotary deserves.
Fitment Note: Mazda RX-8 models require an automatic counterweight (Part # CW-MZD-03) for proper installation. Not included.

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.
