5000 Series T3 2-Piece Rotor with Aluminum Hat

The DBA DBA52320BLKS is a high-performance, two-piece brake rotor from the 5000 Series T3 line, designed to offer superior stopping power and heat management for demanding applications. This rotor is constructed with an ultra-lightweight 6061 T6 aviation aluminum center hat, which not only reduces unsprung weight but also enhances vehicle control and minimizes hub heat. The hat and its rings can be purchased separately for simplified maintenance and repairs. The rotor's surface features T3 slots, which are designed to remove dust and gases, thereby improving pedal feel and braking performance. The high-carbon alloyed iron used in the rotor undergoes Thermal Stability Profiling (TSP) to realign its microstructure during heat treatment, resulting in a more stable and durable component capable of withstanding increased stress and heat generated during intense braking. DBA's patented Kangaroo Paw vane design is a key feature of the 5000 Series T3 rotors. This innovative ventilation system, consisting of 144 diamond and teardrop-shaped pillars, provides up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs. Additionally, the rotor is equipped with temperature-sensitive paint markings that change color at varying heat levels, serving as a visual indicator of rotor fatigue and helping to prevent overheating. The rotor material is high carbon, and it features a coated surface with a slotted style and a vented type. Its dimensions include an outside diameter of 380 mm, a nominal thickness of 34 mm, and a center hole diameter of 68 mm.
