If you're looking to up your game on the track or just want something that can handle the heat of spirited driving, the ACT GM4-HDR6 HD/Race Rigid 6 Pad Kit is where it's at. This isn't just another clutch kit; it's designed for those who appreciate the finer details of performance. You’ve got ACT’s Heavy Duty pressure plate, which is built to take a beating while giving you that extra clamp load you need. Thanks to its unique diaphragm design, you get less deflection and maximized clutch life. Seriously, these things are heat-treated in a four-stage process to ensure they can handle whatever you throw at them.

The 6-pad rigid race discs are made from high-quality ceramic friction materials, which means they can take the heat without breaking a sweat. Plus, the chrome-moly hub is heat-treated too, so you know it’s built to last. The lightweight design means quicker shifts and a more responsive feel, but be warned—engagement is a bit harsher. If you’re looking for something that allows for faster shifting, this is your ticket. Just keep in mind, this setup is recommended for larger clutch sizes since it absorbs more heat, making it perfect for those high-performance applications.
