The DBA 4000 Series plain rotor for 2002–2004 Infiniti I35 front applications is a direct-replacement rotor cast from XG-150 high carbon alloyed iron and processed with Thermal Stability Profiling. DBA’s Kangaroo Paw ventilation design uses 144 diamond and teardrop pillars to increase surface area and cooling efficiency—delivering up to a 30% increase in surface area and about 20% improved cooling—while the HD finish preserves a smooth OE-style look.
