What is the benefit of the Kangaroo Paw ventilation system?

The Kangaroo Paw ventilation system uses 144 diamond and teardrop-shaped pillars. This design increases the rotor's surface area by up to 30% and improves cooling efficiency by 20% compared to traditional straight vane rotors, helping to prevent brake fade.

What material is this rotor made from?

This rotor is cast from XG-150 high carbon alloyed iron. This specific metallurgy is chosen to handle the increased stress and heat generated during intense braking applications.

Does this rotor come with hardware?

This product listing is for the brake rotor only. Installation hardware, such as lug nuts or brake pads, is typically sold separately and should be checked for compatibility.

Product Details

If you're looking to replace the rear brake rotors on your 2010-2023 Lexus GX460, this 4000 Series HD rotor from DBA is a solid option. It's built with XG-150 high carbon alloyed iron, which helps it handle the extra stress and heat that comes with frequent braking, especially during demanding use. This material choice means the rotor can stand up to repeated braking cycles without losing its effectiveness.

What really sets these rotors apart is DBA's patented Kangaroo Paw ventilation system. Instead of standard straight vanes, this design uses 144 diamond and teardrop-shaped pillars. This unique pattern increases the surface area by up to 30% and improves cooling efficiency by 20% compared to traditional designs. This enhanced cooling is crucial for preventing brake fade and keeping your stopping power consistent, even when you're pushing your vehicle hard. The HD variant offers a smooth, OE-style finish, making it a popular choice for drivers who want the performance benefits of the 4000 Series but prefer a factory look, like those found in controlled race divisions.
