The Brembo big brake kit for 2015–2023 Ford Mustang GT front applications combines six-piston billet calipers with 405x34 two-piece rotors finished in nickel and using slotted Type‑1 faces. As a GTR BBK front assembly, it’s offered for direct replacement on Mustang GT models where larger calipers and two-piece rotors are specified to handle increased braking demands.
