GiroDisc 2015+ Ford Mustang S550 Slotted Rear Rotors

Direct replacement for OE brake discs, these lightweight, high-performance 2-piece rotors are designed for the 2015-2022 Ford Mustang GT and Ecoboost. They maintain factory brake bias and ABS efficiency, working seamlessly with OE calipers without modifications. The central hat is made from U.S. sourced 6061-T6 aircraft-spec aluminum, while the disc is proprietary cast iron, poured and machined in-house by Girodisc in the USA. Features 72 curved directional vanes for efficient cooling and a fully-floating mount system with 8 or 10 high-strength alloy steel drive pins and anti-noise spring washers to prevent rattle and allow for heat expansion. This design ensures silent street operation, track readiness, and allows the rotor to self-center between the pads. The cast iron rotor ring can be replaced independently.
