The ACT HD/Race sprung 4-pad clutch kit for 2006 Mazda MX-5 Miata pairs ACT's heavy-duty pressure plate with a spring-centered 4-pad race disc engineered for smaller engines. The diaphragm-style pressure plate increases clamp load and reduces deflection through a four-stage heat-treat process, while spring-centering damps torsional vibration for quieter operation. The kit favors quicker shifts with firmer engagement suited to smaller disc sizes.
