The DBA 4000 Series Plain Rotor is a high-performance automotive brake rotor designed for optimal durability and cooling efficiency. Cast from XG-150 high carbon alloyed iron and undergoing advanced Thermal Stability Profiling, this rotor is engineered to withstand increased stress and heat generated during intense braking. Its construction allows for repeated high-stress applications, making it suitable for demanding driving conditions. Featuring DBA’s patented Kangaroo Paw ventilation system, the rotor incorporates 144 diamond and teardrop-shaped pillars that significantly enhance surface area and improve cooling by up to 20% compared to traditional straight vane designs. This innovative ventilation design helps prevent brake fade and maintains consistent braking performance under heavy use. The rotor’s smooth OE-style finish provides a clean, factory-like appearance, ideal for drivers seeking the benefits of a performance rotor without sacrificing the stock look, especially in controlled race divisions. The inclusion of thermal paint markings offers visual verification of thermal performance, while moisture-proof corrosion protection packaging ensures long-lasting reliability. This direct replacement rotor is suitable for a range of BMW 3 Series models from 1998 to 2000, including the 318i, 318ti, 323Ci, 323i, 323is, and 328i, providing an excellent upgrade for enhanced braking performance and longevity. Whether for street or light racing applications, this rotor combines advanced metallurgy with innovative ventilation technology to deliver superior braking efficiency, durability, and a factory-like appearance.
