The Competition Clutch ultra-light steel flywheel for 1994–2005 Mazda Miata is an 11lb one-piece unit intended to promote quicker revving for forced-induction, track, and rally use. Suited to Stage 3 and up clutch applications, it reduces rotating mass to help the engine respond faster while maintaining a usable engagement. Machined from 4140 forged steel with a one-piece construction; not all models offer both ST and STU versions.
