The DBA 4000 Series drilled and slotted rear rotor with black hat for 2012–2020 Volkswagen Golf R employs XG-150 high-carbon alloyed iron, Thermal Stability Profiling, and Kangaroo Paw ventilation. That combination increases surface area and cooling efficiency versus traditional vane designs, while the XS drill/slot layout and black hub provide improved pad gas escape and a distinctive aesthetic for the Golf R application.
