Paragon Performance 2-piece Rotors offer superior braking and cooling efficiency optimised for track and race applications. Directional ventilation vanes create suction, turbulence, and guide cool air through the rotor for improved heat dissipation and increased resistance to cracking under harsh track conditions.
Made from CM-250 special formulated high carbon alloy cast iron, these rotors deliver optimal bite, excellent thermal characteristics, high-temperature strength, and long-term durability. Rotor rings are heat treated to release internal stress, then turned by state-of-the-art CBN surface machining to ensure better break-in with new brake pads.
Lateral run-out is kept within 0.03mm and balance variations within 2 grams, ensuring vibration-free performance. The fully-floating 2-piece design allows thermal expansion while keeping the rotor self-centred with the pads. Slotted face pattern improves braking consistency, dissipates heat and gases, and provides a clear advantage in wet conditions over blank rotors.
Aluminium hats are CNC machined from lightweight 6061-T6 aerospace grade aluminium, then black hard coat / hard anodised (Mil-spec Type III) for maximum wear and corrosion resistance. Direct bolt-on fitment — no modifications required. Compatible with OEM ABS and brake system, maintaining factory brake bias.
