The Action Clutch Stage 4 single-plate kit for 2003–2006 Subaru Baja 2.5L (EJ253) Non-Turbo uses an unsprung MIBA ceramic disc with a heavy-duty diaphragm pressure plate and reinforced drive straps for rapid engagement and high durability. Intended for dedicated race use, it may introduce clutch chatter that diminishes after proper break-in. Each kit is hand-assembled and quality-checked, and it improves holding capacity by about 170% compared with the factory kit.
