What is the Kangaroo Paw ventilation system?

The Kangaroo Paw is DBA's patented ventilation design that uses a series of diamond and teardrop-shaped pillars. This pattern increases the rotor's surface area and improves airflow for better cooling compared to traditional straight vane designs.

What material are these rotors made from?

These rotors are cast from XG-150 high carbon alloyed iron. This specific alloy is chosen for its ability to withstand the higher stresses and temperatures generated during demanding braking situations.

Do these rotors come with hardware?

This product listing is for the brake rotors only. Installation hardware, such as lug nuts or brake pads, is typically sold separately. Refer to the manufacturer's installation guide for a complete list of required components.

About this part

Product Details

If you're looking to upgrade the braking performance on your Audi or Volkswagen, these DBA 4000 Series XD rotors are a solid option. They're built with a high-carbon alloyed iron, specifically XG-150, which is cast to handle the extra heat and stress that comes with harder braking. This material, combined with DBA's Thermal Stability Profiling, helps the rotors stand up to repeated heavy use.

What really sets these rotors apart is DBA's patented Kangaroo Paw ventilation system. Instead of traditional straight vanes, this design uses a pattern of diamond and teardrop pillars. This increases the surface area by up to 30% and improves cooling efficiency by 20% over standard designs, helping to keep your brakes cooler and performing more consistently, especially during spirited driving or track use. The non-directional cross-drilled and dimpled pattern on the XD finish also adds to the cooling and gives your vehicle a sportier look.

These rotors are designed as a direct replacement for a range of Audi and Volkswagen models, including the Volkswagen GTI, Audi Q3, and Volkswagen Arteon, among others. They fit vehicles equipped with the 340mm front rotor size, so be sure to check your specific application to confirm fitment.
