AERO-ROTOR ASSEMBLY

High-performance replacement rotor ring specifically for StopTech C43 CBK (Competition Big Brake) brake kits. Features a floating 2-piece design with directional ventilation vanes and a slotted surface, optimized for track and race applications. Constructed from CM-250 special formulated high carbon alloy cast iron for superior thermal stability, optimal bite, and increased resistance to cracking. Heat-treated and precision-machined for durability, reduced vibration, and improved break-in. Enhances cooling efficiency by up to 30% and reduces operating temperature by 30% compared to OE rotors, minimizing brake fade and judder. Lighter than most OEM rotors, improving unsprung mass and handling.
