The DBA 4000 Series XS Gold Cross Drilled and Slotted Rear Rotor is engineered for high-performance applications, offering superior heat dissipation and braking effectiveness for Subaru Impreza WRX STI models from 2001 to 2007. Cast from XG-150 high carbon alloyed iron, this rotor is designed to withstand intense braking conditions, ensuring durability and consistent performance. The thermal stability profiling process enhances the rotor’s ability to handle repeated stress and high temperatures, making it suitable for aggressive driving, track use, or heavy-duty street applications. The rotor features DBA’s patented Kangaroo Paw ventilation system, with 144 diamond and teardrop-shaped pillars that significantly increase surface area and improve cooling efficiency by up to 20%, reducing brake fade and maintaining optimal braking performance during demanding conditions.
