Girodisc Ferrari 488 Challenge Evo Rear Iron Rotor Conversion
The Girodisc A2-285 Rear Iron Rotor Conversion is designed as a direct replacement upgrade for the Ferrari 488 Challenge Evo, delivering exceptional braking performance and improved longevity over the OEM carbon ceramic setup. This precision-engineered 2-piece iron rotor system provides the durability, heat tolerance, and serviceability demanded by professional teams and track-day enthusiasts alike.
High-Performance Engineering
Each rotor assembly combines a lightweight 6061-T6 aluminum hat with a high-carbon cast iron ring developed exclusively by Girodisc. This configuration maintains the original brake balance while drastically reducing consumable costs associated with replacing factory carbon rotors. The result is a reliable, high-performing rotor that performs consistently under extreme racing temperatures.
Advanced Cooling and Floating Design
The 48 curved directional vanes inside the rotor act as a centrifugal pump, drawing air through the hub to maximize cooling efficiency and prevent heat-related distortion. Girodisc’s signature floating mount system uses cadmium-plated steel drive pins, secured by class 12.9 cap screws and Belleville washers. This allows the iron ring to expand freely with temperature changes while eliminating rattle and noise.
