DBA 4000 Series plain rear rotor for 2003–2012 Infiniti FX35 is a direct-replacement rotor cast from XG-150 high-carbon alloyed iron and treated with Thermal Stability Profiling to handle repeated heavy braking. It features DBA's Kangaroo Paw ventilation—144 diamond and teardrop pillars—boosting surface area up to 30% and improving cooling roughly 20% versus straight vane rotors. The HD variant preserves a smooth OE-style appearance for a factory look.
