The DBA 4000 Series plain rotor for 2007–2013 Mazda Mazdaspeed3 front applications is a direct-replacement rotor cast from XG-150 high-carbon alloy iron and processed with Thermal Stability Profiling. Its Kangaroo Paw ventilation with 144 pillars increases surface area and cooling efficiency, delivering up to 30% more surface and around 20% improved cooling compared with straight vane rotors. The HD finish maintains a smooth OE-style appearance for restrained looks.
