The DBA 4000 Series Heavy-Duty Plain Rotor is engineered from high-quality XG-150 high carbon alloyed iron, ensuring durability and thermal stability under demanding braking conditions. Featuring DBA’s patented Kangaroo Paw ventilation system, this rotor incorporates 144 diamond and teardrop patterned pillars to optimize heat dissipation and surface area. This advanced design provides up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane rotors, making it ideal for high-performance or heavy-duty applications. The smooth OE-style finish offers a clean, factory look suitable for drivers seeking a balance between performance and appearance, especially in controlled race divisions or street-driven vehicles.
