The DBA 4000 Series plain rear rotor for 2015–2017 Chevrolet SS is a direct-replacement rotor intended for reliable stopping under repeated use. Cast from XG-150 high carbon alloyed iron and thermally profiled, it resists heat-related degradation. DBA’s Kangaroo Paw ventilation with 144 diamond and teardrop pillars raises surface area and cooling efficiency versus straight vanes, and the HD finish variant preserves a smooth OE-style look for drivers who prefer a stock appearance.
