What is the benefit of the T3 slot design?

The T3 slot design helps to keep the rotor surface clean by clearing away brake dust and gases. This ensures that the brake pads maintain consistent contact with the rotor surface, leading to more reliable stopping power.

How does the Kangaroo Paw ventilation improve cooling?

The Kangaroo Paw ventilation system uses a unique pattern of diamond and teardrop-shaped pillars instead of traditional straight vanes. This design increases the surface area and airflow through the rotor, which helps to dissipate heat more effectively than standard rotor designs.

Does this rotor come with a pair or is it sold individually?

This product listing is for a single rear brake rotor. If your vehicle requires two rear rotors, please ensure you order the correct quantity.

Product Details

DBA is known for making well-built brake components, and their 4000 Series T3 slotted rotors are a popular choice for drivers looking for improved stopping power. This rear rotor is designed as a direct replacement for a range of Audi and Porsche models, including the Audi A6, Audi A7, and Porsche Macan. It's built to handle the extra heat and stress that comes with harder braking, making it a solid option for anyone who wants more confidence behind the wheel.

What sets these rotors apart is the material and the cooling design. They're cast from XG-150 high-carbon alloyed iron, which is known for its ability to withstand higher temperatures. After casting, they go through a process called Thermal Stability Profiling to further improve their heat handling. On top of that, DBA uses their patented Kangaroo Paw ventilation system. Instead of traditional straight vanes, this design uses a series of diamond and teardrop-shaped pillars, which DBA says increases the surface area and cooling efficiency by up to 30% and 20% respectively compared to standard rotors. The T3 slotting pattern also helps to keep the rotor surface clean and clear of gas and dust, ensuring consistent braking performance.
