The DBA 4000 Series plain rear rotor for 2003–2008 Nissan 350Z with Brembo brakes is a direct-replacement rotor cast from XG-150 high-carbon alloyed iron and processed with Thermal Stability Profiling to resist stress and heat under repeated braking. Its Kangaroo Paw ventilation employs 144 diamond and teardrop pillars to increase surface area and cooling efficiency roughly 20% over straight-vane designs, and the HD plain finish provides a restrained OE-style appearance.
