The DBA 4000 Series plain rotor for 1989–1993 Nissan Skyline GT-R R32 front applications is a direct-replacement rotor cast from XG-150 high carbon alloyed iron and Thermally Stability Profiled. Its Kangaroo Paw ventilation uses 144 diamond and teardrop pillars to raise surface area and cooling efficiency—yielding up to 30% more surface area and around 20% improved cooling—while the HD finish provides a smooth OE-style appearance.
