The DBA 4000 Series Heavy Duty Rear Brake Rotor is engineered from XG-150 high carbon alloyed iron, offering exceptional thermal stability and durability under intense braking conditions. This rotor undergoes Thermal Stability Profiling (TSP) to ensure consistent performance, even during extended driving or racing applications. Featuring DBA’s patented Kangaroo Paw ventilation system, it incorporates a series of 144 diamond and teardrop patterned pillars that significantly enhance heat dissipation and surface area, providing up to a 30% increase in cooling efficiency compared to traditional straight vane designs. This advanced design reduces brake fade, prolongs rotor life, and maintains optimal brake performance during demanding driving conditions.
