The DBA 4000 Series plain rear rotor for 2001–2005 Lexus IS300 is a direct-replacement rotor cast from XG-150 high-carbon alloyed iron and heat-treated with Thermal Stability Profiling to resist stress and heat during repeated braking. Its Kangaroo Paw ventilation with 144 diamond and teardrop pillars boosts surface area and cooling efficiency over straight-vane designs, and the HD plain face preserves a clean OE-style appearance.
