The DBA 4000 Series drilled rear rotor for 2015–2020 Ford Mustang GT with Performance Package is a direct-replacement disc cast from XG-150 high-carbon alloyed iron and treated with Thermal Stability Profiling. DBA's Kangaroo Paw ventilation improves surface area and cooling, while the XD cross-drilled and dimpled finish enhances heat dissipation and adds a sportier visual compared with HD plain rotors.
