Porsche Boxster Brake Rotor (1) - Front - DBA - 4000 Series HD - `01-`12. A direct-replacement front rotor from DBA's 4000 Series HD, offering the material and cooling advantages of DBA engineering while retaining a smooth OE-style finish.

This rotor is cast from XG-150 high carbon alloyed iron and undergoes DBA's Thermal Stability Profiling (TSP) to resist brake fade under repeated heavy use. It uses DBA's patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars to increase surface area and improve cooling compared to traditional straight vane designs. The 4000 Series HD delivers the performance benefits of the Series while maintaining an OE look favored in controlled race divisions and street-driven performance cars.
