What is the Kangaroo Paw ventilation system?

The Kangaroo Paw is DBA's patented internal vane design. It uses a series of 144 diamond and teardrop-shaped pillars to increase surface area and improve airflow for better cooling compared to traditional straight vane rotors.

What material is this rotor made from?

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

Does this rotor come with any hardware?

This product listing is for a single rear brake rotor only. Installation hardware, such as mounting bolts or brake pads, is typically sold separately.

About this part

Product Details

This is the rear brake rotor you get with the DBA 4000 Series HD kit for your 2001-2005 Mazda Miata. It's a smooth, OE-style rotor designed to handle the extra heat and stress that comes with harder driving, while still looking like a factory replacement. DBA uses a special high carbon alloyed iron called XG-150, which is known for its ability to stand up to increased braking demands without warping.

What really sets these rotors apart is DBA's patented Kangaroo Paw ventilation system. Instead of typical straight vanes, this design uses 144 diamond and teardrop-shaped pillars inside the rotor. This unique pattern increases the surface area by up to 30% and improves cooling efficiency by 20% compared to standard rotors. This means your brakes can stay cooler and perform more consistently, especially during spirited driving or track use.
