The DBA 4000 Series plain rotor for 1990–1999 Nissan Maxima front applications is a direct-replacement rotor that follows DBA’s XG-150 high carbon alloyed iron casting and Thermal Stability Profiling. Kangaroo Paw ventilation, with 144 diamond and teardrop pillars, increases surface area and cooling efficiency—up to a 30% surface area gain and about 20% improved cooling—while the HD variant preserves an OE-style smooth rotor face.
