What is the main benefit of the Kangaroo Paw ventilation system?

The Kangaroo Paw ventilation system uses a unique pattern of pillars to increase surface area and improve cooling efficiency by up to 20% compared to traditional straight vane designs. This helps manage heat buildup during braking.

Why would I choose the HD variant with an OE style finish?

The HD variant offers the performance advantages of DBA's 4000 Series rotors but with a smooth, original equipment look. This is often preferred for street use or in racing series that require a stock appearance.

What is the material of this brake rotor?

This rotor is cast from XG-150 high carbon alloyed iron. This specific metallurgy is chosen for its ability to withstand the increased stress and heat generated during demanding braking applications.

About this part

Product Details

When you're looking to replace the rear brake rotors on your 2004-2011 Mazda RX-8, this DBA 4000 Series HD rotor is a solid option. It's cast from XG-150 high carbon alloyed iron, which is known for its ability to handle the extra stress and heat that comes with hard braking, time after time.

What sets DBA rotors apart is their patented 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 by up to 30% and improves cooling efficiency by 20% compared to traditional designs, helping to keep your brakes performing consistently.

This particular rotor has a smooth, OE-style finish, making it a popular choice if you want the performance benefits of the 4000 Series but prefer a look that's closer to the original equipment, which is often required in controlled race divisions.
