The ACT Heavy Duty pressure plate for the 1990 Honda Prelude increases clamp load and reduces diaphragm deflection to extend clutch life under higher loads. Its precision cover stamping provides consistency while diaphragms undergo a four-stage heat-treat process. The plate raises clamp load roughly 20–50% and is recommended for use with street or race discs; ACT backs it with a one-year warranty.
