Product Description

The **DBA 42962S 4000 Series T3 Front Brake Rotor** is a direct-replacement, performance-focused rotor designed for front brake applications on the **2007-2013 MazdaSpeed3** featuring the 2.3L turbocharged engine. Its advanced tri-symmetrical T3 slot pattern increases exit points for brake pad gases and dust, improving pad bite and helping maintain consistent stopping performance under street or spirited driving conditions. The patented Kangaroo Paw ventilation system enhances heat dissipation compared with standard OEM rotors, reducing the risk of heat-related brake fade.

Constructed from premium XG-150 high carbon alloyed iron and treated with Thermal Stability Profiling (TSP), the DBA 42962S resists stress and warping under repeated heavy braking, delivering durable performance and smoother pedal feel. Precision machine-turned finishes help reduce thickness variation, increasing longevity and reliability. Finished with corrosion-resistant painted non-friction areas and universal uni-directional slot design, this rotor is an excellent performance upgrade for MazdaSpeed3 owners looking for enhanced brake response and heat management over stock components.
