DBA's Kangaroo Paw ventilation design delivers significantly improved braking performance under all conditions to make you safer than ever before. The innovative Kangaroo Paw design outperforms traditional straight vane disc brake rotors and allows your brakes to runs cooler. Traditionally, heat is removed as air flows through the rotor passing between straight cooling vanes. However, the straight vane design does not provide the ideal conditions for heat to be dissipated and tends to trap heat. The Kangaroo Paw features 144 precisely positioned diamond and tear-drop pillars which create a exceptionally strong, reliable, and efficient cooling system. The increased surface area created by the pillars allows for very rapid heat dissipation. DBA's Kangaroo Paw ventilation system quickly removes the heat as cool air flows in from the center of the disc while hot air is forced to the outside of the disc, cooling the discs and return your braking system to optimal operating temperature.
