What is the Kangaroo Paw ventilation system?

The Kangaroo Paw is DBA's patented ventilation design that uses 144 diamond and teardrop-shaped pillars. This unique pattern increases the rotor's surface area and improves cooling efficiency by up to 20% over traditional straight vane designs, helping to dissipate heat more effectively.

Why choose the 'HD' version of this rotor?

The 'HD' (Heavy Duty) variant features a smooth, OE-style rotor finish. This makes it a popular choice for drivers who want the performance advantages of DBA's 4000 Series rotors but prefer a factory look, which is often required for controlled race divisions or simply for street applications.

What material is this rotor made from?

This rotor is cast from XG-150 high carbon alloyed iron. This specific metallurgy is chosen to withstand the increased stress and heat generated during intense braking applications, contributing to its durability and performance.
