Product Description

The DBA 4000 Series XS Drilled & Slotted Rear Brake Rotor (DBA4419XS) is a performance-oriented direct replacement rotor engineered for the rear brakes of the 2003-2006 Mitsubishi Lancer Evolution 8 and 9. With a cross-drilled and slotted surface pattern, this rotor is designed to improve heat dissipation, enhance brake pad bite, and evacuate brake dust and gases more effectively than standard rotors. The drilled holes increase surface area and airflow, while the slots help maintain consistent braking performance under demanding driving conditions.

Built from high carbon alloyed iron and processed with Thermal Stability Profiling (TSP), the DBA4419XS rotor offers improved resistance to thermal cracking and warping, making it well-suited to spirited street driving and occasional track use. Its universal bi-directional design fits either left or right rear position, and the thermo-graphic heat paint markings provide visual feedback on operating conditions. Sold individually, this rotor allows selective replacement or a full rear axle upgrade to boost braking confidence and performance.
