DBA T3 4000 series brake rotors are designed and built for performance and durability.

Features:

- Patented Kangaroo Paw pillar vane venting increases strength and heat dissipation
- XG150 High Carbon Alloyed Iron improves strength, thermal capacity, and thermal stability
- Proprietary TSP heat treatment process stabilizes new castings and improves quality
- Slotted friction surface increases pad bite and minimizes glazing
- Thermo-Graphic paint markings for effective heat monitoring

Disc Brakes Australia has worked for decades with race teams, manufacturers, and users to develop and refine their brake rotor products. All processes, from tooling and vane design to alloys, heat treating and packaging, are controlled by DBA to produce some of the highest quality brake rotors for performance applications.

DBA rotors start with their Kangaroo Paw vane design that features 144 diamond and teardrop patterned pillars (or columns) instead of more typical straight cooling vanes. This design can increase cooling efficiency by up to 20%. These pillars are center split and evenly distributed across the disc face to make the rotor stronger, more stable and more consistent in operation. DBA then uses a specific heat treated XG-150 cast iron alloy in all of its premium performance disc brake rotors. This iron is higher in carbon and specifically alloyed and heat treated to improve thermal characteristics.

The T3 4000 series rotors are slotted as shown. Slotting can reduce pad glazing and allow better pad bite under hard braking conditions. It can also help maintain the pad friction surface by wiping debris generated from hard braking.
