Ford Focus RS Brake Rotor (1) - Rear - DBA - 4000 Series HD - `17-`18. This direct-replacement rear rotor pairs DBA engineering with an OE-style smooth finish for drivers who want upgraded thermal performance while keeping a stock appearance.

Cast from XG-150 high carbon alloyed iron and processed with DBA’s Thermal Stability Profiling (TSP), the 4000 Series HD is built to withstand repeated high-stress braking events. The rotor uses DBA’s patented Kangaroo Paw ventilation — a pattern of 144 diamond and teardrop pillars — which increases surface area and improves cooling when compared to traditional straight vane designs. The HD variant keeps a plain, OE-style face while offering the material and thermal benefits valued in controlled track environments and spirited street driving. Each rotor comes with Thermo-graphic paint markings (THGP) and moisture-proof corrosion protection packaging for reliable storage and handling.
