DBA 4000 Series T3 Slotted Brake Disc Rotor fits Mazda DBA43766S

DBA 4000 Series T3 Slotted Brake Rotors

DBA 4000 Series T3 Slotted brake rotors are engineered for drivers demanding improved braking performance, durability and thermal stability. Designed for performance street vehicles, 4WDs and demanding driving conditions, these rotors deliver consistent braking response under increased thermal loads.

Manufactured from DBA's proprietary XG-150 high-carbon alloyed iron, the 4000 Series combines advanced metallurgy, precision machining and specialised heat treatment to maintain rotor stability through repeated heating and cooling cycles.

Features & Benefits

• T3 Tri-Symmetrical Slotting: DBA's patented slot design helps remove brake dust, gases and debris from the pad contact surface, promoting consistent friction and responsive braking.
• XG-150 High-Carbon Alloyed Iron: Proprietary rotor material engineered for improved thermal stability, durability and resistance to heat-related stress.
• Thermal Stability Profiling (TSP): A specialised heat treatment process that helps reduce internal stresses and improve rotor stability under demanding braking conditions.
• Cubic Boron Nitride (CBN) Grinding: Precision finishing of the braking surfaces promotes consistent pad contact, smooth braking response and reduced vibration.
• Kangaroo Paw Ventilation (where fitted): DBA's patented internal ventilation design promotes efficient heat dissipation compared with conventional straight-vane rotor designs.
