DBA 4000 Series plain rear rotor for 2011–2013 Infiniti QX56 is a direct-replacement rotor cast from XG-150 high-carbon alloyed iron and processed with Thermal Stability Profiling to manage repeated heavy braking. It employs the Kangaroo Paw ventilation pattern with 144 diamond and teardrop pillars to increase surface area up to 30% and improve cooling roughly 20% versus straight vane rotors. An HD variant offers a smooth OE-style finish if a factory look is preferred.
