TAG Motorsports is pleased to offer the GiroDisc Ferrari 458, 488 Challenge Front 2-Piece Iron Rotor Conversion (Carbon Ceramic Replacement) (part number A1-183) for the Ferrari 458 Challenge, Ferrari 488 Challenge, Ferrari 488 Challenge Evo.

Fitment Note: This iron conversion requires the D1405 pad shape. Do not use the factory carbon ceramic pads with these iron rotors.

These GiroDisc 2-piece rotors are direct replacements for the carbon ceramic front rotors on the Ferrari 458 & 488 Challenge factory race cars. Our conversion is compatible with the factory calipers, and does not require any modifications outside of changing the rotors and pads.

The rotor rings are machined from a proprietary casting made of high-carbon iron formulated to GiroDisc's specifications. This superior metallurgy results in a rotor that better withstands hard use, and the curved vanes act as a centrifugal pump pulling air in through the hub to cool the discs. The 2-piece design has a reusable hat which can be installed onto new rings when they need to be replaced.

All major components including the hats, rotor rings, and drive pins are manufactured in-house at our facility in Bellingham, WA from domestically-sourced materials. The hat is made from 6061-T6 aluminum and coated in a type 3 clear anodize finish. The drive pins are made from a high-strength steel alloy and cadmium-plated for corrosion resistance. All rotors are assembled with spring clips and spring washers for race-ready float while also being street-friendly with no noise from loose hardware.
