DBA 4000 Series front rotor for Subaru rally and gravel applications combines XG‑150 high‑carbon alloy iron with Thermal Stability Profiling to withstand repeated high‑stress braking. The rotor uses patented Kangaroo Paw ventilation—144 diamond and teardrop pillars—to increase surface area and cooling efficiency versus straight‑vane designs, and the 4000 HD finish gives a smooth, OE‑style appearance for controlled race use.
