DBA 4000 Series REAR Rotors for 08-09 EVO X

Disc Brakes Australia (DBA) offer a three different series of brake rotors: Their entry level Street Series, mid-range 4000 Series and top of the line, two-piece 5000 Series. No matter what type of driving your car sees, DBA makes a rotor for your application.

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 is stronger, outperforms traditional straight vane disc brake rotors and allows your brakes to runs cooler. Every time the brakes are used massive pressure is built up through the braking system. The force your foot applies at the brake pedal is multiplied many times at the disc rotors, creating friction and extreme heat. 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. These pillars 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, ready to deliver optimum performance every time you step on the brakes.

4000 SERIES: The DBA 4000 Series rotor is a mid-level brake rotor that has more than enough performance for any street driven car and will work very well on a weekend track toy or autocrosser. DBA 4000 Series rotors feature Thermal Stability Profiling (TSP) for improved heat handling. TSP enhances the micro-structure of the rotor material providing greater thermal stability. Increasing the thermal stability allows your DBA rotors to take more heat, making them more stable under heavy, frequent braking. DBA rotors with TSP will, ultimately, improve brake pad and rotor life.

Thermo-Graphic paint markings on the edge of DBA's 4000 Series rotor change color at specific temperature thresholds allowing you to check your braking performance quickly and easily. Green changes to white at 856F, orange will change to yellow at 1022F and the red will change to white after 1166F. Ideal braking temperatures are between 850F and 1000F (so the green will become white and the orange and red are unchanged).
