The DBA 4000 Series rear slotted rotor is a single‑piece direct replacement made from XG‑150 high‑carbon alloyed iron with Thermal Stability Profiling. It uses DBA's Kangaroo Paw ventilation architecture with numerous pillar shapes to increase surface area and boost cooling efficiency. The T3 bi‑directional slot pattern further aids heat management and consistent pad contact for improved braking under demanding conditions.
