What is the benefit of the Kangaroo Paw ventilation system?

The Kangaroo Paw system uses 144 diamond and teardrop-shaped pillars. This design increases the rotor's surface area and improves cooling efficiency by up to 20% compared to traditional straight vane rotors, helping to manage heat during braking.

Are these rotors directional?

No, these rotors feature DBA's T3 bi-directional slot design. This means they can be installed on either the left or right side of the vehicle and will function effectively.

What material are these rotors made from?

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

Product Details

Starting with XG-150 high carbon alloyed iron, these DBA 4000 Series T3 rotors are built to handle the heat. The material itself is chosen for its ability to stand up to the stresses of repeated hard braking, which is crucial for keeping your Sienna stopping reliably. They also feature DBA's Kangaroo Paw ventilation system, which uses 144 diamond and teardrop pillars to increase surface area and improve cooling by up to 20% over standard straight vane designs.

The T3 slotting pattern on these rotors is bi-directional, meaning they work effectively no matter which way the rotor spins. These slots help to sweep away brake dust and gases, which keeps the pad surface cleaner and allows for more consistent braking performance, especially during demanding use. As a direct replacement part, they are designed to fit right into your vehicle's existing brake system without modification.
