DBA DBA43051XD-10 4000 Series XD Cross-Drilled Dimpled Rear Brake Rotor

The DBA 4000 Series XD Cross-Drilled and Dimpled brake rotor delivers enhanced braking performance for high-performance street and track applications. Engineered specifically for Subaru WRX STI models equipped with Brembo 6-piston Spec R yellow calipers and 19-inch wheels (04/2017 and later), this rear rotor combines DBA's proven thermal stability with advanced heat dissipation technology.

Key Features:

• Cross-drilled and dimpled surface pattern enhances heat dissipation and reduces brake fade
• 4000 Series XD construction features Thermal Stability Profiling (TSP) for consistent performance
• Kangaroo Paw ventilation technology increases airflow by up to 20% over standard rotors
• T3 slot design with 144 diamond and tear slot edge peripheries for superior pad bite
• Direct OEM replacement fitment for hassle-free installation
• Manufactured from high-carbon iron alloy for excellent wear characteristics
• Sold individually (order quantity needed for complete axle service)

DBA's 4000 Series rotors are precision-machined to exacting tolerances and feature a corrosion-resistant coating on non-friction surfaces. The cross-drilled pattern aids in wet weather performance by expelling water, gases, and debris from the rotor surface, while the dimpled design provides additional bite points for the brake pad. This rotor is ideal for enthusiasts who demand maximum stopping power for both spirited street driving and occasional track use.
