The DBA 4000 Series plain rotor for 2006–2007 Mazda Mazdaspeed6 rear applications is a direct-replacement rotor cast from XG-150 high-carbon alloy iron with Thermal Stability Profiling. DBA's Kangaroo Paw ventilation uses 144 diamond and teardrop pillars to increase surface area and cooling efficiency, achieving up to 30% more surface and about a 20% cooling improvement versus straight vanes. The HD option preserves an OE-style smooth finish for controlled appearance.
