These DBA 4000 Series T-Slot Slotted Rotors utilize High Carbon Iron (XG-150) and Thermal Stability Profiling (TSP) allowing constant extreme heat cycles designed for those "late braking scenarios". 4000 XS and 5000 XS provides improved braking performance, better brake pedal feel and with the benefit of looking the part as well. Inspired within Australia’s heartland, DBA developed the Kangaroo Paw cooling system. This patented ventilation system provides a much more efficient method of keeping the rotors cool under the heaviest of braking applications. Using a series of 144 diamond and teardrop patterned pillars (or columns) instead of conventional straight cooling vanes, the design increases cooling efficiency by up to 20% when compared with most other conventional ventilated disc rotors. As well as providing cooler conditions, the Kangaroo Paw system also provides additional support to the friction face. This enables the rotor to maintain the fine tolerances over the life of the rotor better than a straight vane design, which can “balloon” and swell between the vanes when operating at high temperatures.
