The DBA 4000 Series T3 front rotor is a direct replacement slotted rotor for 2012+ VW Golf R (MK7) and Audi S3 applications. Cast from XG-150 high carbon alloyed iron and thermal-stability profiled, it uses DBA’s Kangaroo Paw ventilation and bi-directional T3 slots to improve cooling and fade resistance. Tests show up to a 30% increase in surface area and roughly 20% better cooling vs straight vane designs.
