DBA DBA4910S 4000 Series T3 Slotted Front Brake Rotor

The DBA DBA4910S is a front 4000 Series T3 slotted disc brake rotor from Disc Brakes Australia (DBA), engineered as a direct-fit, single-piece performance upgrade over standard OE brake rotors. Designed for drivers who demand improved stopping power on the street and in high-performance applications, this rotor delivers advanced braking technology in a bolt-on replacement format.

Key Features:

• T3 Tri-Symmetrical Slot Design: Features 48 precise, CNC-machined tri-symmetrical curved slots — an upgrade over the T2's 32-slot design — for a quieter, more responsive, and smoother brake pedal feel. Slots increase the exit points for friction dust and gases, improving consistency and effectiveness on every stop.
• Kangaroo Paw Ventilation: DBA's patented pillar vane design uses 144 diamond and teardrop-shaped pillars to achieve up to a 30% increase in surface area and up to 20% improvement in cooling efficiency compared to traditional straight-vane rotors.
• XG-150 High Carbon Alloyed Iron: Cast from a premium iron alloy that improves strength, thermal capacity, and resistance to warping and cracking under sustained heavy braking.
• Thermal Stability Profiling (TSP): A proprietary DBA heat treatment process that subjects new castings to controlled heat cycles, relieving internal manufacturing stresses to maximize rotor stability and reduce metal fatigue in demanding applications.
• Thermo-Graphic Heat Paint (TGHP): Color-coded paint markings on the rotor's outer edge change color at predetermined temperature thresholds, allowing drivers to monitor peak braking temperatures and make informed decisions about pad selection.
• Corrosion Protection: All non-friction surfaces are painted to prevent rust and maintain appearance.
• Non-Directional Design: Symmetrical slotting allows a single rotor to be used on either side, simplifying installation and inventory.

The DBA 4000 Series T3 is DBA's recommended slotted rotor for high-performance street driving and demanding off-road applications. As with all DBA rotors, the DBA4910S is a direct bolt-on replacement requiring no mechanical modifications. Sold individually.
