The DBA 4000 Series T3 Slotted Brake Rotor is engineered from high-quality XG-150 high carbon alloyed iron, ensuring durability and heat resistance for demanding driving conditions. This rotor features DBA’s patented Kangaroo Paw ventilation system, which incorporates 144 diamond and teardrop patterned pillars to maximize surface area and enhance cooling efficiency by up to 20% over traditional designs. Such advanced features help manage heat buildup during intense braking, providing consistent performance over multiple stops. Built as a direct replacement, this rotor is suitable for various driving applications, including street, performance, 4×4, SUV, track days, rally, and armored vehicles, making it a versatile upgrade for enthusiasts and professionals alike. The rotor’s thermal stability profiling (TSP) ensures long-term structural integrity under high-stress conditions while the thermographic paint markings aid in installation and quality assurance. Featuring the revolutionary T3 bi-directional slot design, the rotor improves brake pad gases and dust evacuation, resulting in a quieter, more responsive brake pedal feel and increased braking effectiveness. This universal slot design eliminates the need for separate left and right rotors, simplifying installation and maintenance. The rotor’s corrosion-resistant packaging and moisture protection help preserve its quality during storage and transport, ensuring optimal performance upon installation. Whether for high-performance driving or daily commuting, the DBA 4000 Series T3 slotted rotors deliver exceptional stopping power, heat dissipation, and durability for your BMW 3 Series and 4 Series from 2013 to 2015.
