The Clutch Masters 07-13 Mazda 3 Mazdaspeed 850 PRO Series Twin Disc Clutch with Steel Flywheel is a high-performance multi-disc clutch designed to deliver exceptional strength, durability, and consistent engagement. Featuring a 8.50" (216mm) diameter unit, it incorporates a "Sprung Race" stage with a sprung ceramic disc and a "Rigid Race" stage with a rigid ceramic disc, both utilizing ceramic friction materials capable of handling intense street or track abuse. The clutch employs a next-generation driven hub with a 12-point nut and stud mounting system, replacing traditional aluminum setups with heat-treated steel for unmatched structural integrity. This design reduces flex, wear, and failure under extreme torque and heat, while the re-engineered hub ensures faster installation, cleaner alignment, and reliable engagement, minimizing spline wear and maximizing performance.

Designed for vehicles from 2007 to 2013, including Mazda 3 and Mazdaspeed models, this clutch serves as a direct replacement or upgrade for enhanced performance in demanding driving conditions. Suitable for street, track, or racing applications, it is engineered to withstand serious abuse while maintaining smooth engagement. The kit includes the twin disc clutch assembly and a steel flywheel, both SFI Certified to meet industry standards. Installation is straightforward for qualified technicians, making it an ideal choice for enthusiasts seeking increased torque capacity, improved response, and long-term reliability in high-performance driving scenarios.
