Alright, let’s talk about the ACT HD/Perf Street Sprung Kit, specifically the HC6-HDSS version. If you're looking to upgrade your clutch setup, this kit is a solid choice. It features ACT's heavy-duty pressure plate, which is pretty much their bread and butter. What makes it stand out? Well, the exclusive diaphragm design cranks up the clamp load while keeping deflection in check, which means you get a longer-lasting clutch that can handle some serious power.
Every diaphragm goes through a four-stage heat treatment process. Trust me, that’s not just marketing fluff—it really does enhance performance and durability. The pressure plate itself is built like a tank, with precision cover stampings that ensure rigidity and consistency. You won’t have to worry about it flexing under pressure.
Now, let’s get into the performance street disc. This baby is made with premium organic materials, packed with high copper content. What does that mean for you? Better heat transfer and a steel-backed lining that boosts burst strength and durability. Plus, it’s designed with reduced marcel, so you’ll notice quicker shifts, which is a game-changer whether you’re on the street or the track.
