If you're looking to step up your clutch game, the ACT Sport/Perf Street Sprung Kit (CA1-SPSS) is worth checking out. This kit is all about delivering a solid upgrade without making your daily drive a pain. The sport pressure plate in this setup uses a unique diaphragm design that ramps up the clamp load while minimizing deflection. What does that mean for you? Better clutch life and a smoother engagement, plain and simple.
One of the standout features is the four-stage heat-treating process that every diaphragm goes through. This isn't just some marketing fluff—it's designed to give you performance that lasts. The pressure plates are made with precision cover stampings, so you know they’re built to hold up under pressure. And if you’ve ever dealt with a clutch that fades under heat, you’ll appreciate the premium organic materials in the performance street discs. High copper content means better heat transfer, and the steel-backed lining adds durability. Plus, they’ve got a reduced marcel for quicker shifts, which is a game-changer on the track or the street.
Now, if you’re worried about noise or reliability, you can breathe easy. This kit is designed for quiet operation while still packing a punch in terms of strength. Whether you’re hitting the streets or taking it to the track, this clutch has got your back.
