The ACT Sport/Race HW4‑SPR6 clutch kit for 1990 Honda Civic combines a Sport pressure plate and a 6‑pad rigid race disc intended for competition use. The pressure plate’s exclusive diaphragm design increases clamp load and reduces deflection, with diaphragms undergoing a four‑stage heat‑treating process for durability. The rigid 6‑pad disc uses ceramic friction and a heat‑treated chrome‑moly hub for quicker shifts and higher heat capacity, with a one‑year warranty included.
