The DBA 4000 Series plain front rotor for 2001–2005 Lexus IS300 is a direct-replacement rotor cast from XG-150 high-carbon alloyed iron and processed with Thermal Stability Profiling to handle repeated heavy braking. DBA's Kangaroo Paw ventilation with 144 diamond and teardrop pillars increases surface area and improves cooling efficiency compared with traditional straight-vane rotors, while the HD plain finish retains a smooth OE-style look.
