DBA's mid-level 4000 Series Rotors are designed for serious braking performance on the street or on the track. Their 6x6 wiper-slot rotor face is engineered for a clean disc surface with consistent friction and minimal fade. They even come equipped with Thermo-Graphic heat paint for quick, easy monitoring of your rotor temperatures.
The cross-section of DBA 4000 Series Rotors doesn't look like your every day vented disc. What you'd see is Disc Brake Austraila's patented "Kangaroo Paw" system - a complicated array of 144 pillars, arranged specifically to vent hot air quickly and provide superior structural stability. The Kangaroo Paws, combined with a directional 6x6 wiper slot design and Thermo Stability Profiling, give you a cool, clean rotor surface for supreme bite and long brake life. Finally, jet-black paint on the center of the rotor protects it from rust and corrosion and looks great in your wheel wells.
