01-05 Mazda Miata DBA Brake Rotors

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.


Street Series

DBA's entry level, enhanced performance rotor, the Street Series, offers improved braking straight out of the box. DBA's Street Series slotted or drilled and slotted rotors improves pad bite and assists to reduce brake fade by evacuating gases created when pads contact the rotor. DBA Slotted Street Series are the perfect replacement rotor for the performance conscious street motorist.

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 experience improved 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 856°F, orange will change to yellow at 1022°F and the red will change to white after 1166°F. Ideal braking temperatures are between 850°F and 1000°F (so the green will become white and the orange and red are unchanged).
