The DBA 4000 Series rotor is their mid-level brake rotor that performs better the top-level rotors from other brands.  The 4000 series is capable as a street rotor but is also at home on the race track. 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).

T3 Slot 48 precision CNC machined slots

• Tri-Symmetrical curve slots dampens the vibration harmonics or noise – A quieter, responsive and smoother brake pedal feel
• Increased number of out-gassing exit points for brake pad friction gasses to escape through – Increases the consistency and effectiveness of every brake stop
• Universal slot design – Eliminates the need for left and right discs

Kangaroo Paw – 144 diamond and tear drop pillar ventilation system

• Increased surface area resulting in greater heat dissipation – Minimises brake fade and increases braking effectiveness
• Increased surface area resulting in greater heat dissipation – Prolongs service life for both pads and rotors. Reduces mechanical damage and associated costs

XG150 High Carbon Alloyed Iron

• An increase in thermal capacity property allows the rotor to handle constant extremes of heat over extended periods of time – Minimises warping and cracking and prolongs the service life of the rotor
• Special formulation designed to respond to DBA’s TSP process – Minimises warping and cracking and prolongs the service life of the rotor

Thermographic Temperature Monitoring

• Heat paint markings change colour at specific temperature thresholds – Offers the driver a clear indication of peak braking temperatures
• When temperature thresholds are exceeded paint markings will permanently change colours – Allows the driver to monitor rotor fatigue and decide on rotor replacement and to assist resellers with warranty claims

Paint protection on non-friction areas

• Reduces corrosion – Stops any unsightly rust formation
• Enhances appearance – Adds value to the product
