4000 Series XS Brake Rotor

The DBA 4000 Series XS brake rotor is engineered by Disc Brakes Australia, a leading manufacturer of performance aftermarket brake components. Constructed from high carbon alloyed iron, the DBA 4000 Series XS rotor undergoes Thermal Stability Profiling (TSP). This process enhances the rotor's metallurgy to withstand the increased stress and heat generated during intense braking applications. The rotor features DBA's patented Kangaroo Paw ventilation system, utilizing 144 diamond and teardrop-shaped pillars. This design provides up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs, ensuring consistent performance under demanding conditions. The DBA42225XS rear rotor has an outside diameter of 330 mm, a nominal thickness of 22 mm, and a height of 59 mm. It features a vented design with a drilled and slotted surface and a 5-lug hole pattern. The center hole diameter is 80 mm, and the discard thickness is 22 mm. The rotor is made from high carbon and heat-treated iron. This specific rotor, DBA42225XS, is compatible with the 2008 and 2014 Mitsubishi Lancer Evolution Models, whether they are equipped with a 1-piece or 2-piece disc system.
