Mazda 3 Brake Rotor (1) - Front - DBA - 4000 Series Plain - `04-`13 is a direct-fit front replacement rotor for 2004–2013 Mazda 3 models. It pairs an OE-style smooth finish with DBA’s race-informed metallurgy for reliable everyday and spirited driving.

Cast from XG-150 high carbon alloyed iron and produced using Thermal Stability Profiling (TSP), this DBA 4000 Series HD rotor is engineered to resist heat fade and maintain dimensional stability under repeated heavy use. The patented Kangaroo Paw ventilation uses 144 diamond and teardrop patterned pillars to increase surface area and improve airflow; DBA reports up to a 30% increase in surface area and a 20% improvement in cooling efficiency versus traditional straight vane designs. The smooth OE-style finish makes this rotor popular for drivers who want performance benefits without a race-only appearance. Each rotor ships with moisture-proof corrosion protection and THGP thermo-graphic paint markings for quality verification and ease of inspection.
