The Competition Clutch ultra-light steel flywheel for 2002–2008 Acura RSX and 2002–2009 Honda Civic Si is an 11lb one-piece unit machined to reduce mass and aid quicker revving for forced-induction or track-oriented builds. Suited to Stage 3 and higher clutch applications, it improves engine response while remaining a direct replacement. Built from 4140 forged steel; availability of ST and STU versions varies by application.
