4000 Series HD 330mm Rear Rotors

The DBA 4000 Series HD rotors are premium one-piece brake rotors engineered for demanding street use and occasional track days. Constructed from high-carbon alloy iron (XG-150) and subjected to heat treatment and Thermal Stability Profiling (TSP), these rotors are built to withstand the increased stress and heat generated during intense braking, offering exceptional resistance to cracking and thermal distortion. Thermographic paint is applied to aid in temperature management during heavy use. The vented rotor design ensures efficient cooling under demanding conditions. This specific rotor (DBA42165) has an outside diameter of 330mm and a nominal thickness of 25mm. It is designed as a direct replacement for the rear of the 2015-2023 Ford Mustang GT, Bullitt, and Mach 1 models. Compatibility notes indicate specific fitment for the 2015 Mustang GT with or without the Performance Package (which includes Brembo front discs) and for 2017-2018 Mustang GT with or without the Performance Package. These rotors are sold individually.
