What is the benefit of the Kangaroo Paw ventilation system?

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

What is the advantage of the T3 slotting on this rotor?

The T3 slotting is bi-directional and helps to sweep away dust and gas that can build up between the brake pad and rotor. This keeps the rotor surface cleaner and ensures a more consistent and reliable braking performance, especially under demanding conditions.

What material is this rotor made from and why is it important?

This rotor is cast from XG-150 high carbon alloyed iron. This specific alloy is chosen for its ability to withstand the higher temperatures and stresses generated during intense braking applications, helping to prevent warping and maintain braking performance over time.

Product Details

DBA is known for making well-built brake components that stand up to hard use. This T-Slot T3 4000 Series rotor is a prime example, designed as a direct replacement for performance-oriented vehicles like the Audi S3, VW Golf R MK7, and many others. If you're looking to improve your braking performance, especially under demanding conditions, this rotor is a solid choice.

What sets this rotor apart is its construction and cooling design. It's cast from XG-150 high carbon alloyed iron, which is chosen for its ability to handle the extra stress and heat that comes with spirited driving or track use. This material, combined with DBA's Thermal Stability Profiling process, helps prevent warping and maintain braking consistency. The standout feature is the patented Kangaroo Paw ventilation system. Instead of traditional straight vanes, it uses a unique pattern of 144 diamond and teardrop pillars. This design significantly increases the surface area and improves airflow, leading to up to a 30% increase in surface area and a 20% improvement in cooling efficiency over standard rotors. The T3 slotting is also bidirectional, helping to keep the rotor surface clean and providing a consistent bite for your brake pads.

This is a single-piece rotor, meaning it's a straightforward replacement for your factory units. It fits a wide range of popular performance vehicles, including models like the Audi S3, Volkswagen Golf R MK7, and Volkswagen GTI. When you're ready to upgrade your braking system, this DBA rotor offers a noticeable improvement in heat management and braking feel.
