Mazda 3 Mazdaspeed Twin Disc Clutch Kit – Clutch Masters 850 PRO Series (2007–2013). A compact 8.50 in twin-disc system designed for serious street and track use, supplied with a Clutch Masters steel flywheel.

Built on the FX 850 PRO platform, this conversion kit replaces the OEM interface with a 12-point nut-and-stud mounting system and a heat-treated steel 12-post foundation for strength and stability under heat and torque. The next-generation single, precision-driven hub aids faster installation, cleaner alignment, and consistent engagement that helps reduce spline wear. Ceramic friction materials provide positive bite and durability, with Sprung Race (PTD80) or Rigid Race (PTD8R) options. SFI certified for motorsport safety standards.
