DBA (Disc Brakes Australia) Disc Brakes Australia - better known by their initials DBA - are a highly-respected designer and manufacturer of top-quality high-performance disc brake rotors. Over four decades their commitment to innovation and quality backed by intensive research and development has firmly entrenched DBA as a global player in the technology-driven world of superior disc brake rotor solutions. No matter what you drive - be it a daily-driver 4WD commercial vehicle weekend toy or a track-only weapon - DBA's range of disc brake rotors can truly enhance the stopping power of your car. DBA - Technology At Work From the beginning of a disc brake rotor's manufacturing process at the foundry right through to the final machining regimen DBA have invested heavily in the know-how and infrastructure to create world-leading products. Their own proprietary cast iron formulation - known as XG-150 - is a carbon-rich creation that when combined with another of their techniques Thermal Stability Profiling (TSP) results in extremely strong disc brake rotor castings which possess excellent thermal conductivity properties just what you want in a disc brake rotor! The final step in production is another area where DBA excel via their use of Cubic Boron Nitriding (CBN) a refining process which leaves the disc brake rotor with a surface finish that is far superior to a conventionally-ground surface found on other rotors. Superior Ventilation DBA are perhaps best known for their "Kangaroo Paw" ventilation system. Instead of a series of straight vanes centrally located within each rotor casting DBA's patented method of using 144 Kangaroo Paw-shaped pillars as the central component of each rotor casting better ensures rotor temperatures stay within optimum range by more efficiently channeling air through the rotor core than straight vanes can. Not only do they enable better ventilation the Kangaroo Paw pillars also give better support to the friction surfaces of the rotor enabling better performance strength and stability whilst also providing more thermal mass than a rotor with straight vanes boosting efficiency and performance even further.
