4000 Series XD Rear Left Disc Brake Rotor

The DBA DBA42164XD is a 4000 Series XD disc brake rotor, engineered as a direct replacement upgrade for drivers seeking performance braking beyond standard OE levels. It features DBA's non-directional, cross-drilled and dimpled rotor design, which offers enhanced structural support compared to traditional cross-drilled techniques. The XD finish not only contributes to superior cooling, providing extra thermal management benefits over the HD finish, but also enhances the rotor's sports aesthetics. These rotors are constructed from high-carbon alloyed iron and undergo Thermal Stability Profiling (TSP) to ensure they can withstand increased stress and heat generated during intense braking applications without warping or vibration, thus minimizing brake fade and improving pedal feel. Key specifications include an outside diameter of 352mm, a nominal thickness of 32mm, and a vented rotor type with 5 lug holes. The rotor surface is drilled and slotted for optimal performance. This DBA 4000 Series XD brake rotor is compatible with various Ford Mustang models from 2015, 2017, and 2018, specifically the GT trims without the Performance Package, for the front position. It is noted that rotor configurations are not recommended for heavy off-road use.
