Action Clutch 12-15 Honda Civic Si 2.4L (K24Z7) Stage 4 Clutch Kit (1MD) w/Lightened Flywheel

Action Clutch's Stage 4 (1MD) Clutch Kit is engineered for extreme durability and peak performance in challenging race conditions. It features a heavy-duty single diaphragm pressure plate, reinforced drive straps, and an unsprung MIBA ceramic (available in a 4 or 6 puck) disc. This kit provides quicker engagement, which may result in some clutch chatter that will minimize after proper break-in. The kit is suitable for low/mild horsepower vehicles and is ideal for dedicated race applications, including drag, road, and drift racing. It boasts a torque holding capacity of 376 ft/lbs and requires the use of Hondata FlashPro. Each kit undergoes rigorous quality checks by experienced engineers. What's included: Unsprung MIBA Ceramic 6 Puck Disc, Single Diaphragm HD Pressure Plate, Pilot Bearing / Bushing (when applicable), Clutch Alignment Tool, Conventional Release Bearing, and a Lightened Flywheel. Break-in requirements are 500 street miles, keeping RPMs under 4500, no more than half-throttle, and no boost (if applicable) to retain warranty and ensure longevity. Disclaimers note that ceramic-based clutch discs prioritize holding capacity and durability over extended life expectancy in street driving, which can lead to premature wear due to harsher engagement and increased slippage. Unsprung clutch kits are not recommended for daily/street use or constant on/off engagement environments as they can cause premature wear to the clutch disc hub.
