If you're looking to step up your clutch game, the ACT Z64-HDSS Heavy Duty/Performance Street Sprung Kit is worth checking out. This isn't just any clutch kit; it combines the best of both worlds with a heavy-duty pressure plate and a street-friendly disc. The pressure plate features an exclusive diaphragm design that cranks up the clamp load, which means less deflection and a longer lifespan for your clutch. Plus, each diaphragm goes through a four-stage heat treatment, giving you some serious performance under pressure.
Now, let's talk about the disc. The Performance Street disc is made with premium organic materials that have a high copper content, which helps with heat transfer. It’s got a steel-backed lining for that extra burst strength and durability. And if you’re someone who likes to shift quickly, you’ll appreciate the reduced marcel for faster engagement. It’s engineered to work seamlessly with the ACT pressure plates, so you know you’re getting reliability when it counts.
