2018-2021 Subaru STI

Upgrade your braking system with the DBA 5000 Series XD Black 2-Piece Rotor — a premium performance rotor built for serious driving and long-term durability. This rotor features a cross-drilled and dimpled friction face to improve bite and remove gas and brake dust efficiently. It’s supported by a Kangaroo Paw vane design that boosts cooling by dramatically increasing ventilation surface area.

The two-piece construction pairs a high-carbon cast-iron rotor ring with a lightweight T6061-T6 aluminum hat. This reduces unsprung weight, improves heat management, and helps maintain braking strength under demanding conditions. Hardware includes NAS-standard bolts and crimp nuts, ensuring strength and reliability.

The XD finish isn’t just about looks: its combination of drilled holes and dimples helps manage structural stress better than traditional drilling, and provides additional cooling capacity over standard heavy-duty finishes. Non-friction areas are coated to resist corrosion and maintain a clean, aggressive look.
