What is the Kangaroo Paw ventilation system?

DBA's Kangaroo Paw ventilation is a unique design featuring 144 diamond and teardrop patterned pillars. This system increases the rotor's surface area and improves cooling efficiency by up to 20% compared to traditional straight vane designs, helping to dissipate heat more effectively.

What is Thermal Stability Profiling?

Thermal Stability Profiling is a heat treatment process that DBA applies to their rotors. It helps the high carbon alloyed iron handle the increased stress and heat generated during intense braking, improving the rotor's durability and performance under demanding conditions.

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 sold separately. Please refer to the manufacturer's installation instructions for any specific hardware requirements.

About this part

Product Details

When you're pushing your 2018 or 2021 Subaru WRX hard, especially on the track or during spirited driving, the rear brakes are working overtime. This 4000 Series HD rear brake rotor from DBA is built to handle that extra stress and heat.

It's cast from XG-150 high carbon alloyed iron, which is known for its ability to manage the increased demands of intense braking. DBA also uses a process called Thermal Stability Profiling to further prepare the metal for these conditions. What really sets this rotor apart is the Kangaroo Paw ventilation system. Instead of traditional straight vanes, it uses a unique pattern of 144 diamond and teardrop pillars. This design significantly increases the surface area and improves cooling efficiency by up to 20% compared to standard rotors, helping to prevent brake fade.

This particular rotor has a smooth, OE-style finish, making it a popular choice for drivers who want the performance benefits of the 4000 Series but prefer a more subtle look, like those found in controlled race divisions.
