What is the Kangaroo Paw ventilation system?

The Kangaroo Paw is DBA's patented ventilation design that uses 144 diamond and teardrop-shaped pillars. This system increases surface area and improves cooling efficiency by up to 20% compared to traditional straight vane rotors, helping to dissipate heat more effectively.

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 hardware?

This product listing is for the brake rotor only. Installation hardware, such as lug nuts or brake pads, is typically sold separately. Please refer to the manufacturer's installation guide or consult with a parts specialist for recommended hardware.

Product Details

If you're looking to replace the front brake rotors on your Lexus GS, IS, or SC, this DBA 4000 Series HD rotor is a solid option. It's built with a high-carbon alloyed iron casting, specifically XG-150, which helps it handle the extra heat and stress that comes with harder braking. This material is well-suited for drivers who push their vehicles a bit, whether on the street or in controlled race environments.

What really sets these rotors apart is DBA's patented Kangaroo Paw ventilation system. Instead of standard straight vanes, it uses a series of 144 diamond and teardrop-shaped pillars. This design significantly increases the surface area and improves cooling efficiency by up to 20% compared to traditional rotors. This means better heat dissipation, which helps prevent brake fade and keeps your braking performance more consistent, especially during extended use. The rotor itself has a smooth, OE-style finish, so it looks like a factory part but performs much better.

This rotor is designed to fit a range of Lexus models from the late 90s through the mid-2000s, including the GS300, IS300, and SC430, among others. It's a direct replacement for your stock rotor, making installation straightforward.
