The DBA 4000 Series standard rear rotor for 2005–2008 Porsche Boxster S (iron rotor) is cast from XG-150 high carbon alloyed iron and undergoes Thermal Stability Profiling to handle repeated high-stress braking. It features DBA’s Kangaroo Paw ventilation that increases surface area and cooling efficiency compared to traditional straight vane designs, and the HD variant preserves a smooth OE-style finish for controlled appearance.
