4000 Series Standard Brake Rotor

The DBA 4000 Series Standard Brake Rotor is engineered by Disc Brakes Australia as a direct replacement for drivers seeking enhanced braking performance beyond standard OE levels. Constructed from high carbon alloyed iron, these rotors are treated with Thermal Stability Profiling (TSP) to ensure they can withstand the increased stress and heat generated during intense braking applications. This process allows the metallurgy to maintain its integrity under demanding conditions. DBA incorporates its patented Kangaroo Paw ventilation system into the 4000 Series rotors. This unique design utilizes a series of 144 diamond and teardrop-shaped pillars, which significantly increases the rotor's surface area and provides up to a 20% improvement in cooling efficiency compared to traditional straight vane designs. This advanced cooling capability is crucial for preventing brake fade and maintaining consistent stopping power. This specific rotor, DBA42308, is designed for the front application and measures 320mm in outside diameter with a vented, smooth surface type. The key technical specifications include a center hole diameter of 68 mm, a nominal thickness of 28 mm, and an overall height of 49.2 mm. It is designed with 5 stud/lug holes. The DBA 4000 Series Standard Brake Rotor is compatible with a wide range of Infiniti and Nissan vehicles. Specific fitment notes include requirements like 'Standard Brakes; Iron Calipers' for certain Nissan 370Z models, 'SE-R' for the 2005-2006 Nissan Altima, and specific caliper and disc size details for various Infiniti models. Always consult the detailed fitment list to ensure compatibility with your vehicle's specific configuration, as variations can occur based on year, submodel, trim, and production date.
