4000 Series Standard Brake Rotor

The DBA 4000 Series Standard Brake Rotor is engineered by Disc Brakes Australia (DBA) as a direct replacement upgrade for drivers who demand enhanced braking performance beyond factory specifications. Constructed from a high carbon alloyed iron and subjected to Thermal Stability Profiling (TSP), this rotor is built to withstand the rigorous demands of intense braking applications. A key feature of the DBA 4000 Series is its patented Kangaroo Paw ventilation system. This innovative design utilizes a series of 144 diamond and teardrop-shaped pillars, resulting in a significantly increased surface area and up to a 20% improvement in cooling efficiency when compared to conventional straight vane rotors. This enhanced thermal management helps to prevent brake fade and maintain consistent stopping power. This specific rotor (DBA42724) is a front rotor with a smooth surface type and a vented rotor design. Its technical specifications include an outside diameter of 354 mm, an overall height of 83.5 mm, a nominal and discard thickness of 32 mm, a center hole diameter of 112 mm, and 5 stud/lug holes. The DBA42724 is compatible with a range of Toyota Tundra, Land Cruiser, and Lexus LX570 models, primarily from the 2007-2022 model years. A specific fitment note mentions that for 2016-2017 Toyota Land Cruiser models in the USA, it applies to the 353.5mm disc variant.
