5000 Series T3 2-Piece Brake Rotor

The DBA DBA52962BLKS is a 2-piece brake rotor from the 5000 Series T3 line, designed for high-performance applications. This rotor shares the advanced technology found in DBA's 4000 Series but is presented in a two-piece configuration. Key features include an ultra-lightweight 6061 T6 aviation aluminum center hat/bell, which enhances vehicle control and minimizes hub heat. The aluminum hat is anodized to resist rust and maintain a clean appearance. The rotor itself is constructed from high-carbon iron with a realigned microstructure achieved through heat treatment cycles, ensuring stability and longevity. For enhanced performance and safety, the DBA52962BLKS features T3 slots and/or chamfered drill holes. These work together to efficiently remove dust and gasses, contributing to a more confident and responsive pedal feel. The rotor also includes paint markings that change color at specific temperature levels, providing a visual indicator of rotor fatigue. This rotor is recommended for performance street use, track events, and extreme/fleet duty applications. It is designed to fit 2007-2011 Mazda 3 Mazdaspeed models with the 2.3L Turbocharged engine.
