DBA DBA42656XS-10 4000 Series Brake Rotor

After decades of design and development with race teams around the world Disc Brakes Australia developed a proprietary cast iron ( XG-150 ) for use in all of it premium performance disc brake rotors. This specially formulated iron is rich in carbon and alloyed to produce excellent thermal characteristics which is a key factor in the production of the casting combined with our patented Kangaroo Paw ventilation design. With it supersaturated solution of carbon in an iron matrix the excess carbon precipitates out in the form of graphite flakes. The morphology of these graphite flakes provide excellent thermal properties increasing the thermal shock resistance and allowing it to survive rapid thermal cycling with core-heat levels of approximately 700oC and above.Coupled together with DBA TSP process where the cast iron is stress relieved during the manufacturing process you end up with a cast iron structure ideal for heavy braking and perfect for motorsport applications.4000xs Premium Cross DrilledFeatures : * Patented "Kangaroo Paw" ventilation design* provides greater heat dissipation* XG150 High Carbon Alloyed Iron increases the thermal capacity properties and allows the rotor to handle constant extremes of heat over extended periods of time* TSP (Thermal Stability Profiling) prolongs the service life of the rotor* Non-directional XS cross-drill and slot design eliminates the need for left and right discs* Heat paint markings change colour to monitor peak braking temperatures* Paint protection on non-friction areas protect and enhance rotor appearance
