The DBA 4000 Series plain rotor for 1990–1996 Nissan 300ZX 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 uses 144 patterned pillars to grow surface area and improve cooling—up to 30% more surface area and roughly 20% better cooling efficiency compared to straight vane designs. The HD finish keeps a smooth OE-style look.
