The DBA 4000 Series T3 Slotted Front Rotor is engineered from XG-150 high carbon alloyed iron, offering exceptional thermal stability and durability under intense braking conditions. Undergoing Thermal Stability Profiling, this rotor is designed to withstand the increased stress and heat generated during aggressive driving, making it ideal for performance street, SUV, and light utility applications. The rotor features DBA’s patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars, providing up to 30% more surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs. This enhanced cooling helps maintain optimal brake performance and extends rotor life during demanding driving scenarios.
The 4000 Series T3 rotor incorporates DBA’s signature T3 bi-directional slot design, which features CNC-machined tri-symmetrical slots. These slots provide a quieter, more responsive brake pedal feel and allow for more efficient removal of brake pad friction dust and gases. The universal slot design eliminates the need for left or right rotor configurations, simplifying installation and ensuring consistent performance across all applications. Built for versatility, these rotors are perfect for street driving, track days, rally, and even armored vehicle use, delivering reliable stopping power and heat dissipation.
Each rotor is finished with thermo-graphic paint markings for easy heat monitoring and packaged with moisture-proof corrosion protection to ensure longevity in various climates. The direct replacement design guarantees compatibility with the specified BMW models, providing a hassle-free upgrade for improved braking performance. Whether for daily commuting or high-performance driving, DBA’s 4000 Series T3 rotors offer a high-quality, durable, and efficient braking solution that enhances safety and driving confidence.
