If you're looking to upgrade your Mustang's clutch setup, the ACT FM13-HDSS kit is a solid choice. This isn't just any clutch kit; it's built for those who want something that can handle the heat—literally. The heart of this kit is ACT's Heavy Duty pressure plate, which features a unique diaphragm design. This design boosts clamp load, cuts down on deflection, and helps your clutch last longer. Plus, every diaphragm goes through a four-stage heat-treating process, so you know it’s tough enough for whatever you throw at it.

The Performance Street disc is where things get interesting. Made from high-quality organic materials with a good amount of copper, it’s designed for better heat transfer and durability. The steel-backed lining means it can take a beating without falling apart. And with reduced marcel, you’ll notice quicker shifts that feel crisp and responsive, perfect for both daily driving and spirited weekend runs.
