DBA 4000 Series T3 Slotted Rear Brake Rotor for Select Audi and Porsche 2010-2020 (DBA42847S)

Fits select 2010-2020 Audi A6, A7, Q5, Q7, S4, S5, S7, SQ5, and Porsche Macan models.

The DBA 4000 Series T3 is a high-performance, direct-replacement rear brake rotor engineered for drivers who demand consistent stopping power in both daily driving and performance environments. Featuring DBA’s patented tri-symmetrical T3 slot design, these rotors utilize CNC-machined exit points to effectively clear brake pad friction dust and gases. This results in a smoother, quieter, and more responsive brake pedal feel compared to traditional slotted designs.

Constructed from XG-150 high-carbon alloyed iron, these rotors are built to handle extreme thermal stress without warping or cracking. Each rotor undergoes Thermal Stability Profiling (TSP) to stabilize the iron's microstructure and includes integrated thermo-graphic paint (THGP) markings. These heat-sensitive markings change color at specific temperature thresholds, allowing you to monitor peak rotor heat for better performance management. The universal slot design simplifies installation by eliminating the need for side-specific left and right rotors.

• Tri-Symmetrical T3 Slots: Precisely machined slots increase the number of exit points for dust and gas to escape.
• XG-150 High Carbon Iron: Enhanced material density provides superior thermal capacity and durability.
• Universal Slotting: Symmetrical design allows for use on either the left or right side of the vehicle.
• Thermo-Graphic Monitoring: Built-in paint markings provide visual heat tracking for the braking system.
• Thermal Stability Profiling (TSP): Reduces internal stresses in the iron for improved heat handling.
• Direct Replacement: Designed to bolt directly to factory mounting points with no modifications.
• Manufacturer Part Number: DBA42847S
