GiroDisc Ferrari 458 Challenge Slotted Front Rings

GiroDisc D1-183 380mm front replacement rotor rings are precision-engineered in the USA from a proprietary high-carbon cast iron alloy for Ferrari 458 Challenge, 488 Challenge, and 488 Challenge Evo race cars. Designed for maximum thermal stability and durability in high-performance racing, these direct-fit rings bolt onto existing GiroDisc aluminum hats. The advanced curved directional vane design efficiently pulls air through the disc for enhanced cooling and minimized brake fade. This two-piece floating design allows independent expansion, reducing stress and preventing warping. Slotted surfaces (where applicable) expel brake dust and gases for consistent pad bite. Each pair includes a complete floating hardware kit.
