Infiniti FX35 Brake Rotor (1) - Rear - DBA - 4000 Series HD - `03-`12 is a direct-fit rear replacement rotor designed for 2003–2012 FX35 models. This DBA 4000 Series HD rotor combines high-carbon metallurgy and advanced ventilation for improved thermal control and consistent performance.

Cast from XG-150 high carbon alloyed iron and processed with DBA's Thermal Stability Profiling (TSP), this rotor is engineered to resist the heat and stress of demanding braking. The Kangaroo Paw ventilation uses 144 diamond and teardrop-patterned pillars to increase surface area and airflow, improving cooling versus a traditional straight vane design. The 4000 Series HD offers a smooth OE-style finish for drivers who want the performance benefits of DBA without a drilled or slotted appearance. Rotors arrive with Thermo-Graphic Paint (THGP) markings and moisture-proof corrosion protection packaging for storage and handling.
