Ford Focus RS Brake Rotor (1) - Front - DBA - 4000 Series HD - 2016–2018. This front replacement rotor from DBA’s 4000 Series HD is designed for drivers who want a direct-fit OE-style rotor with upgraded metallurgy and cooling performance for spirited street use and controlled track applications.

Cast from XG-150 high carbon alloyed iron and processed with DBA’s Thermal Stability Profiling (TSP), this rotor is built to withstand repeated high-temperature cycles without unexpected cracking or rapid wear. The Kangaroo Paw ventilation uses 144 diamond- and teardrop-patterned pillars to increase surface area and airflow; DBA reports up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane rotors. The 4000 Series HD version maintains a smooth, OE-style finish favored in controlled race divisions and for owners who prefer a factory look while gaining the thermal benefits of DBA’s design. The rotor includes THGP thermo-graphic paint markings and arrives in moisture-proof, corrosion-protection packaging for storage and handling.
