What is the benefit of the drilled and wavy design on these rotors?

The drilled holes and wavy pattern, combined with DBA's Kangaroo Paw ventilation, help to dissipate heat more effectively. This leads to improved and more consistent braking performance, especially under heavy use, and also gives the rotor a distinct sporty appearance.

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 handle the increased stress and heat generated during demanding braking applications.

Do these rotors come with any hardware?

This product listing is for the brake rotors only. Installation hardware, such as brake pads and any necessary mounting bolts or clips, are typically sold separately. Please refer to the manufacturer's installation guide for a complete list of required components.

About this part

Product Details

If you're pushing your Audi or Volkswagen hard, especially on the track or during spirited drives, keeping your rear brakes cool and performing consistently is key. These DBA 4000 Series XD rotors are built to handle that kind of stress. They feature a unique drilled and wavy design that not only looks sharp but also helps manage heat much better than standard rotors.

DBA casts these rotors from a high-carbon alloy iron, specifically XG-150, which is known for its ability to withstand the high temperatures and stresses that come with aggressive braking. They've also put them through a process called Thermal Stability Profiling to further improve their heat handling. The standout feature is DBA's patented Kangaroo Paw ventilation system. Instead of simple straight vanes, it uses a pattern of diamond and teardrop pillars inside the rotor, which increases the surface area and boosts cooling efficiency by up to 30% compared to traditional designs. This means more consistent braking performance when you need it most.

These rotors are a direct replacement for many Audi and Volkswagen models, including the GTI, Atlas, and Arteon, and are designed to fit right in place of your stock rear rotors. The XD finish adds an extra layer of cooling and a distinct sporty look that complements performance brake setups.
