The DBA 4000 Series drilled and slotted front rotor for 2003–2007 Nissan 350Z and 2003–2004 Infiniti G35 with Brembo brakes uses high-carbon, heat-treated iron and patented Kangaroo Paw ventilation to manage heat and resist warp. The 4000 Series XS Gold variant adds a premium cross-drilled and slotted face plus a gold-finished hub, helping evacuate pad gases and dust while providing an upgraded direct-replacement rotor option.
