What is the benefit of DBA's Kangaroo Paw ventilation?

The Kangaroo Paw ventilation system uses 144 diamond and teardrop-shaped pillars inside the rotor. This design increases the surface area by up to 30% and improves cooling efficiency by 20% compared to traditional straight vane rotors, helping to manage heat during hard braking.

Why choose a plain rotor finish like this one?

This 4000 Series HD rotor has a smooth, OE-style finish. It's popular for drivers who want the performance advantages of DBA's advanced rotor technology but prefer a more traditional, clean look on their vehicle.

What material is this rotor made from?

The rotor is cast from XG-150 high carbon alloyed iron. This specific metallurgy is chosen to better handle the increased stress and heat generated under intense braking conditions.

About this part

Product Details

The cast iron in this front brake rotor is made from XG-150 high carbon alloy, which helps it handle the extra stress and heat that comes with hard braking. This is especially important for a car like the RX-8, where spirited driving is common. DBA has put their patented Kangaroo Paw ventilation system on these rotors. Instead of regular vanes, you'll find 144 diamond and teardrop-shaped pillars inside. This design increases the surface area by up to 30% and boosts cooling efficiency by 20% over standard straight vane rotors, helping to keep your brakes from overheating during demanding use.

This 4000 Series HD rotor has a smooth, OE-style finish, making it a popular choice for drivers who want the performance benefits of DBA's advanced design but prefer a more traditional look. This makes them a solid option for controlled race divisions or just for those who like the clean appearance of a plain rotor. The high carbon alloy iron and the advanced cooling system work together to ensure consistent braking performance, time after time.
