Mazda Mazdaspeed3 Brake Rotor (1) - Front - DBA - 4000 Series HD Plain Rotor - `07-`13 is a direct-fit front rotor engineered for Mazdaspeed3 models from 2007–2013. It delivers the proven metallurgy and cooling design of DBA’s 4000 Series in a smooth OE-style finish for drivers who want performance without a non-stock look.

Cast from XG-150 high carbon alloyed iron and processed with Thermal Stability Profiling (TSP), this DBA rotor resists thermal cracking and maintains structural integrity under repeated heavy use. The patented Kangaroo Paw ventilation uses 144 diamond and teardrop-shaped pillars to increase surface area and improve cooling compared to traditional straight vane rotors. The 4000 Series HD variant offers the braking consistency and corrosion-protective packaging expected from DBA while keeping an OE-style appearance suitable for controlled race divisions or street-driven performance cars.
