Ford S197 Mustang GT500 Front Rotors
Unleash the full stopping power of your 2013–2014 Shelby GT500 with Girodisc 2-piece 72-vane front rotors—purpose-built for high-performance Mustangs. These rotors are a direct OEM replacement, engineered to bolt right up to your factory calipers with zero modifications. With a massive weight savings of nearly 10 lbs per rotor, they dramatically reduce rotational and unsprung mass for quicker acceleration, sharper turn-in, and improved suspension response.
Machined in the USA from U.S.-sourced materials, the Girodisc system pairs a precision 6061-T6 aluminum hat with a proprietary cast-iron rotor ring featuring 72 curved internal vanes. This advanced cooling design acts like a centrifugal pump, pulling air through the rotor to dissipate heat and prevent brake fade during high-speed use—ideal for aggressive street driving and track days alike.
