The ACT HD/Performance Street sprung clutch kit for 1991–2003 BMW E36/E37/E46/E39 combines ACT's Heavy Duty pressure plate with a Performance Street sprung disc. The diaphragm-style pressure plate increases clamp load and reduces deflection; the street disc uses organic materials with high copper content and a steel-backed lining for improved heat transfer and burst strength. The kit targets durable, street-capable clutch upgrades for the listed BMW platforms.
