The Brembo Big Brake Kit for 2015–2023 Ford Mustang rear GTS applications features four‑piston calipers and 380x28mm two‑piece cast slotted Type‑1 rotors in black high‑finish. Designed as a direct rear upgrade, the kit increases rotor and caliper size to improve pad contact and rotor ventilation, helping maintain braking consistency during repeated or heavier stops.
