DBA DBA4786S 4000 Series T3 Slotted Rear Brake Rotor

The DBA 4786S is a high-performance slotted brake rotor from the 4000 Series T3 line, engineered for drivers who demand superior braking performance for spirited street driving, track days, or heavy-duty applications like towing. This direct-fit rear brake rotor combines advanced Australian engineering with premium materials to deliver exceptional stopping power, heat management, and durability.

Advanced Materials and Construction:

• XG150 high-carbon alloyed iron provides exceptional heat resistance and minimizes degradation under extreme conditions
• Thermal Stability Profiling (TSP) process enhances fatigue resistance and reduces surface crazing
• Vented rotor construction with 13.22-inch outside diameter
• Protective black coating on non-friction surfaces prevents rust and corrosion

Performance Features:

• Patented Kangaroo Paw ventilation system with 144 diamond and teardrop-patterned pillars increases cooling efficiency by up to 20% compared to conventional rotors
• T3 tri-symmetrical slot design features curved, gradually overlapping slots that dampen vibration for quiet operation while maintaining consistent pad contact
• Uni-directional slotting effectively disperses gases and debris under heavy braking for improved pedal feel and response
• Heat paint marks allow monitoring of peak brake temperatures

Application: This rotor is designed as a rear brake component and is sold individually. DBA rotors are engineered as direct OE replacements requiring no modifications and are compatible with stock brake calipers, making installation straightforward for professional mechanics.
