Product Description

The DBA 42225XS 4000XS Rear Brake Rotor is a high-performance direct replacement rotor engineered for the Mitsubishi Lancer Evolution X (2008-2015). Designed to upgrade braking performance over standard OEM rotors, it features DBA's patented Kangaroo Paw ventilation system with 144 diamond and tear-drop pillars that increase surface area for up to a 20 % improvement in cooling efficiency compared to straight vane designs. The cross-drilled and slotted surface helps brake pads release heat, dust, and gas more effectively, resulting in more consistent pedal feel and reduced risk of pad glazing during spirited driving or track sessions.

Constructed from high carbon alloyed iron and finished with a CBN machine turn, this rotor offers improved resistance to warping and thickness variation over standard stock rotors, enhancing longevity and performance under repeated heavy braking. The gold-painted hat area provides additional protection against corrosion, while the vented design and precise OEM-matching dimensions ensure a straightforward bolt-on installation. This rotor is ideal for Evo X owners who want a performance-oriented rear braking upgrade without modifying calipers or other brake components.
