The Action Clutch Ironman Unsprung kit for the 2003 BMW Z4 2.5L DOHC RWD pairs a single-plate unsprung disc with a lightened flywheel for track-focused use. It employs American sintered iron friction, a dual clamp-load heavy-duty pressure plate and yields a 250% increase in holding capacity over factory, delivering aggressive on/off engagement intended for race applications only. Some light engagement noise or gear rattle can occur; verify correct kit selection to avoid transmission damage.
