The DBA 4000 Series Heavy Duty Plain Rotor is engineered for high-performance applications, especially suited for Lexus models including the IS, GS, and GS450h from 2010 to 2016. Crafted from XG-150 high carbon alloyed iron and subjected to Thermal Stability Profiling, this rotor offers exceptional durability under intense braking conditions. The high-quality metallurgy ensures the rotor withstands increased stress and heat generated during aggressive driving or heavy-duty use. Its design incorporates DBA’s patented Kangaroo Paw ventilation system, featuring 144 diamond and teardrop-shaped pillars that significantly enhance cooling efficiency and surface area by up to 30% compared to traditional straight vane designs. This results in reduced brake fade and improved overall braking performance, even under demanding conditions. The rotor features a smooth OE-style finish, making it a perfect direct replacement for stock rotors while providing a clean, professional appearance suitable for controlled race divisions or street driving. Additional features include moisture-proof corrosion protection, thermo-graphic paint markings for easy heat monitoring, and compatibility with existing brake components. This rotor is ideal for fleet, truck, and heavy-duty applications where reliable, high-performance braking is essential. Designed to meet or exceed OE specifications, the DBA 4000 Series Heavy Duty Plain Rotor ensures longevity, safety, and enhanced braking capabilities for your Lexus vehicle.
