Designed for high-performance street and track applications, the DBA 4000 Series T3 Slotted Brake Rotor offers exceptional durability and braking efficiency. Cast from XG-150 high carbon alloyed iron, these rotors are engineered to withstand increased stress and heat generated during intense braking, ensuring reliable performance over time. The thermally stable metallurgy undergoes thermal profiling to optimize heat dissipation, reducing brake fade and maintaining consistent stopping power under demanding conditions. Featuring DBA’s patented Kangaroo Paw ventilation, with 144 diamond and teardrop patterned pillars, the rotors provide up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs, helping to extend rotor life and improve brake response. The T3 bi-directional slot design, an evolution of the proven T2 slot, incorporates CNC-machined tri-symmetrical slots that enhance dust and gas evacuation, resulting in quieter operation and a smoother pedal feel. This universal slot pattern eliminates the need for left and right-specific rotors, simplifying installation and ensuring consistent performance. Suitable for performance street driving, SUVs, light utility vehicles, rally, track days, and armored vehicles, these rotors balance advanced engineering with reliable, direct-fit replacement. Each rotor includes thermo-graphic paint markings for quality assurance and moisture-proof packaging for corrosion resistance, making them an ideal upgrade for enthusiasts seeking superior braking performance and durability.
