The Action Clutch Ironman Sprung (Street) kit for the 2003 BMW Z4 2.5L DOHC RWD includes a sprung disc and lightened flywheel designed for aggressive engagement and improved torque capacity. It uses American sintered iron friction, a dual clamp-load pressure plate and patented fully enclosed spring retainers to protect against failures, offering a 250% increase in holding capacity over the factory unit. Though labeled street, this kit is intended for non-daily, high-power applications and may produce light engagement noise.
