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 surface area by up to 30% and improves cooling efficiency by 20% compared to traditional straight vane rotors, helping to reduce brake fade.

Why would someone choose an OE-style finish rotor?

An OE-style finish rotor, like this one, offers the performance advantages of the 4000 Series design but maintains a smooth, factory look. This is often preferred for drivers who want improved braking without changing the appearance of their wheels.

What material is this brake 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.

About this part

Product Details

Cast from XG-150 high carbon alloyed iron, this DBA 4000 Series HD brake rotor is built to handle the heat and stress of frequent braking. The material choice helps it stand up to increased demands, making it a solid option for drivers who push their vehicles. Its smooth, OE-style finish makes it a popular choice for those who want the performance benefits of the 4000 Series without altering the factory look, especially for controlled race divisions.

What really sets this rotor apart is DBA's patented Kangaroo Paw ventilation system. Instead of traditional straight vanes, it uses 144 diamond and teardrop-shaped pillars. This design increases the surface area by up to 30% and improves cooling efficiency by 20% compared to standard rotors. Better cooling means more consistent braking performance, especially during extended use, and helps reduce the risk of brake fade.
