The Ironman Unsprung kit from Action Clutch is an unsprung single-plate solution built for high-powered race vehicles that need maximum torque capacity. It uses American sintered iron friction material and a dual-clamp heavy-duty pressure plate to deliver a strong on/off engagement feel. Not intended for street use, this track-only kit is quality-checked by experienced engineers and provides approximately 250% increased holding capacity for BMW Z4 3.0L (2003–2005).
