Mazda Mazdaspeed3 Brake Rotor (1) - Rear - DBA - 4000 Series Plain - `07-`13. This is a single rear replacement rotor designed for 2007–2013 Mazdaspeed3 2.3L models, offering the construction and durability DBA’s 4000 Series is known for.

Cast from XG-150 high carbon alloyed iron and processed with DBA’s Thermal Stability Profiling (TSP), this 4000 Series HD plain rotor balances strength and consistent performance under repeated heavy braking. The rotor uses DBA’s patented Kangaroo Paw ventilation — a layout of 144 diamond and teardrop patterned pillars — which increases surface area and improves cooling versus traditional straight vane rotors. The HD variant retains a smooth, OE-style finish for drivers who want performance upgrades without a race-styled appearance. Each rotor is marked with Thermo-Graphic Paint (THGP) and packaged to resist moisture for reliable storage and direct-fit replacement.
