What is the benefit of the Kangaroo Paw ventilation system?

The Kangaroo Paw ventilation system uses a unique pattern of 144 pillars to increase surface area by up to 30% and improve cooling efficiency by 20% compared to traditional straight vane rotors. This helps dissipate heat more effectively, reducing the risk of brake fade.

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 typically sold separately and should be confirmed before purchase.

What is the difference between the 4000 Series HD and other DBA rotors?

The 4000 Series HD rotor features a smooth OE-style finish, making it ideal for drivers who want enhanced cooling and durability but prefer a factory appearance. Other DBA series might have different finishes or be designed for more extreme track use.

About this part

Product Details

If you're looking to replace the front brake rotors on your 2018 or 2021 Subaru WRX, this 4000 Series HD rotor from DBA is a solid option. It's built with a high-carbon alloyed iron that can handle the extra stress and heat that comes with harder braking. This rotor is designed to look like a standard OE rotor, making it a popular choice for drivers who want the performance benefits without a radical visual change.

What sets these rotors apart is DBA's Kangaroo Paw ventilation system. Instead of typical straight vanes, this design uses 144 diamond and teardrop-shaped pillars. This unique pattern increases the surface area by up to 30% and improves cooling efficiency by 20% compared to standard straight vane rotors. This means better heat dissipation, which helps prevent brake fade during spirited driving or track use. The rotor itself is cast from XG-150 iron, a well-built material known for its ability to withstand increased thermal loads.
