Product Fitment: 

2004-2017 Subaru STI

Upgrade your braking performance with the DBA 4000 XD Series Drilled and Dimpled Front Rotors—engineered for drivers who demand superior stopping power and reliability beyond OEM capability. These high-performance rotors combine premium materials, unique cooling features, and advanced thermal monitoring to deliver consistent braking under extreme conditions. Ideal for spirited street driving, track sessions, and performance-built vehicles equipped with Brembo Yellow Spec R-Pot calipers.

The 4000 XD Series uses DBA’s tri-symmetrical slot design to improve pedal feel, reduce vibration, and ensure even pad wear. The patented Kangaroo Paw ventilation system dramatically increases surface area for exceptional heat dissipation, minimizing brake fade even during sustained high-temperature use. Finished with corrosion-resistant paint on non-friction surfaces, these rotors maintain both performance and appearance.
