The Brembo GT rear big brake kit for 2015–2023 Mustang GT, V6 and EcoBoost rear applications upgrades the stock rear to four‑piston calipers and 380×28 mm two‑piece cast rotors to enhance stopping stability and thermal control. This variant uses drilled rotor faces and red painted calipers; two‑piece construction aims to simplify rotor servicing and allow targeted replacement of worn rotor faces.
