The Stage 3 (1MS) clutch kit from Action Clutch is built for Honda Civic Si (2006–2011) 2.0L (K20Z3) applications seeking robust durability and quicker engagement. It combines a Sprung MIBA Ceramic disc (available in 4- or 6-puck), reinforced drive straps and a heavy-duty single diaphragm pressure plate to improve holding capacity and control. Some chatter during break-in is normal; kits are inspected by senior engineers before shipment.
