What is the Kangaroo Paw ventilation system?

The Kangaroo Paw ventilation is DBA's patented design that uses a series of 144 diamond and teardrop-shaped pillars. This unique pattern increases the rotor's surface area and improves its ability to dissipate heat compared to traditional straight vane designs.

Does this rotor come with hardware?

This product listing is for the rear brake rotor only. Installation hardware, such as bolts or clips, is typically sold separately. Please refer to the manufacturer's installation guide or consult with a technician for a complete list of required components.

What is the benefit of the high-carbon alloyed iron?

Using XG-150 high carbon alloyed iron allows the rotor to better withstand the increased stress and heat generated during intense braking. This material helps prevent warping and ensures more consistent performance over time.

About this part

Product Details

When you're looking to replace the rear brake rotors on your 2013-2022 Subaru BRZ (excluding models with Brembo brakes), this DBA 4000 Series HD rotor is a solid option. It's built with high-carbon alloyed iron, specifically XG-150, which is known for handling the extra heat and stress that comes with harder braking. This material choice helps ensure the rotor stands up to repeated use without warping.

What really sets these rotors apart is DBA's 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 for airflow by up to 30% and improves cooling efficiency by 20% over traditional designs. This means your brakes can stay cooler and perform more consistently, especially during spirited driving or track days. The HD variant offers a smooth, OE-style finish, making it a popular choice for those who want the performance benefits of the 4000 Series but prefer a factory look, which is often required for certain racing divisions.
