The Z65-HDSS kit comes with ACT's top - selling Heavy Duty pressure plate and well - loved street disc. The ACT Heavy Duty pressure plates use a unique diaphragm design. This design boosts the clamp load, reduces deflection, and greatly extends the clutch's lifespan. All diaphragms go through a four - stage heat - treating process for outstanding performance. The ACT pressure plates have precisely stamped covers for better rigidity and consistency. ACT's Performance Street discs are made of premium organic materials with a high copper content, which helps in better heat transfer. They also have a steel - backed lining for more strength and durability. These discs have less marcel, allowing for quicker shifts to match the ACT pressure plates, offering enhanced strength and reliability.
