The DBA 4000 Series plain rear rotor for 2003–2005 Nissan 350Z (standard brakes) is a direct-replacement rotor cast from XG-150 high-carbon alloyed iron and processed with Thermal Stability Profiling to resist heat and stress under repeated heavy braking. Kangaroo Paw ventilation with 144 diamond and teardrop pillars increases surface area and cooling efficiency compared with traditional straight-vane designs; the HD plain finish preserves an OE-style look favored in controlled race divisions.
