The DBA 4000 Series plain rear rotor for 2014–2016 BMW M235i and M235i xDrive applications is a direct-replacement rotor cast from XG-150 high-carbon alloyed iron and thermally profiled for repeated braking heat. DBA's Kangaroo Paw ventilation increases surface area and cooling through 144 diamond and teardrop pillars, improving heat dissipation versus straight vane rotors while offering an HD smooth-face option to maintain an OE appearance.
