DBA 03-12 Infiniti FX35 Rear 4000 Series Plain Rotor

The DBA 4000 Series HD Brake Disc is a rear replacement rotor cast from XG-150 high carbon alloyed iron. It features DBA's patented Kangaroo Paw ventilation system, which uses 144 diamond and teardrop-shaped pillars. This design results in up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs.

These rotors are a direct replacement upgrade from original equipment brakes. They offer advanced materials, precision manufacturing, and a smooth OE-style finish. The use of Thermo-Graphic Paint markings indicates thermal history.
