DBA 5000 T3 slot design ‘sports’ the same benefits as the 4000 SERIES except for one major structural advancement. The 5000 SERIES brake rotors incorporate Alumalite hats made from 6061-T6 Aeronautical grade aluminium. The Alumalite hat reduces unsprung weight for improved suspension and handling performance as well as allowing uniform expansion of the disc rotor during high performance use. The Alumalite’s ability to reduce the level of heat transfer adds to the longevity of both the disc rotor and other vehicle components such as brake pads and wheel hub bearings.
The tri-symmetrical slots also increase the number of out-gassing exit points for brake pad friction gases to escape through, further increasing the consistency and effectiveness of every brake stop.
Designed for extreme road and race applications.
Home grown inspiration
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.
Dimensionally precise
Friction surface is CBN (Cubic Boron Nitride) machine turned for improved DTV (Disc Thickness variation) and parallelism. This provides a more dimensionally precise and stable surface finish when compared to ‘ground’ finished disc rotors.
Thermo-graphic Temperature Monitoring
4000 and 5000 Series rotors also incorporate DBA’s Thermo-Graphic heat paint markings which change colour when specific temperature thresholds are achieved. By monitoring the markings, drivers can check their braking performance quickly and easily.
High Carbon Alloyed Iron
Through extensive testing and feedback from performance drivers worldwide, DBA has developed a unique cast iron formula (XG-150) for use in all of it’s CLUBSPEC disc brake rotors. The XG-150 formula, with it’s increased thermal capacity properties, is designed to respond to the DBA TSP process allowing the rotor to handle constant extremes of heat over an extended period of time.
Thermal Stability Profiling (TSP)
TSPTM is a process of relieving the stresses that are naturally generated in the casting and manufacturing processes. This process stabilises the stresses by re-aligning the microstructure of the iron, resulting in a disc rotor ideal for heavy road braking and race applications.
