The Brembo rear big brake kit for 2015–2023 Ford Mustang GT, V6 and EcoBoost models upgrades the rear brakes with four-piston billet calipers and two-piece 380×28 mm rotors. This variant uses drilled rotors with a nickel finish, pairing billet calipers and 2pc rotor construction to present a direct-replacement rear braking option for these Mustang variants.
