• 2-piece floating design: lightweight aluminium hat + cast iron rotor ring for better heat dissipation
• Slotted faces and curved-vane venting improve pad bite and reduce fade under repeated use
• Zinc-coated rotor rings resist corrosion; 12 high-strength drive pins maintain float integrity
• Serviceable - swap worn rings only, keep the hat
• Fit all rear calipers including red, silver, gold and M4 CS carbon-ceramic spec
