If you're looking to upgrade your clutch setup, the TK1-HDSS kit from ACT is worth checking out. This isn't just any clutch kit; it combines the best features from ACT s Heavy Duty pressure plate and their most popular street disc. I ve had my fair share of clutches, and let me tell you, this one really stands out. The diaphragm design on the pressure plate is a game changer it ramps up the clamp load, cuts down on deflection, and seriously extends the life of the clutch. Plus, they go through a four-stage heat-treating process that really boosts performance. You can feel the difference when you re pushing it hard on the streets or the track.

The pressure plate itself is built like a tank with precision cover stampings, which means it s rigid and consistent no flexing under pressure. And the Performance Street disc? It s made from premium organic materials with a high copper content, which helps with heat transfer. That means less fade when you re really putting the pedal to the metal. The steel-backed lining gives it extra burst strength, so you know it can handle the heat. I ve noticed the reduced marcel makes for quicker shifts, which is a nice touch, especially in spirited driving situations.

Install Instructions:

  • Light to moderate pedal effort, so it won t wear you out on daily drives.
