The DBA rotors are the same dimensions as stock but the slots help with initial bite and help keep the brakes working consistently as they allow vaporized pad material and dust to escape the pad contact patch under hard braking.
Like most brake rotors, DBA rotors are made of grey cast iron, but DBA’s iron alloy uses has a higher level of carbon with a 25% higher strength than the typical iron used for rotors. This is a superior iron for rotors that have a high surface hardness, crack and warp resistance and a good tolerance for rapid changes in temperature.
DBA rotors feature their unique Kangaroo Paw pillar vane internal construction. The Kangaroo vanes give more support to the surface of the rotor allowing for the friction surface of the rotor to be stiffer under high temperatures than conventional vanes. This gives both better pedal feel and more consistent brake action, and the braking surface stays flatter against the pads. The multiple individual pillars have more internal surface area to help shed heat away from the friction surface as well.
DBA rotors are also subjected to a long and rigorous heat treating process that takes over 24 hours and results in a rotor that is more resistant to warping and the effects of extreme heat.
DBA’s rotors also come pre-marked with temperature indicating paint. The temp paint on the DBA rotors will allow us to see how hot the rotors are getting and will tell us if we need to upgrade the pads as we start building more and more speed with the future upgrades Whiteline has planned for the Mustang.
