4000 Series Standard Rear Vented Brake Rotor

The DBA 4000 Series Standard Brake Rotor is a direct replacement rear rotor engineered for drivers seeking enhanced braking performance beyond standard Original Equipment levels. Manufactured by Disc Brakes Australia (DBA), a premier Australian performance aftermarket brake component producer, this rotor is constructed from high carbon alloyed iron. It undergoes Thermal Stability Profiling (TSP), a process that enhances the rotor's metallurgy to withstand the significant stress and heat generated during demanding braking applications, ensuring consistent performance over time. A key feature of the DBA 4000 Series rotors is the patented Kangaroo Paw ventilation system. This unique design incorporates 144 diamond and teardrop-shaped pillars, which contribute to an increased surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs. This advanced cooling capability is crucial for dissipating heat effectively, preventing brake fade, and maintaining optimal braking performance under load. The DBA42493 rotor is specifically designed as a direct replacement, simplifying installation. Its technical specifications include an outside diameter of 314.9 mm, an overall height of 78.5 mm, a nominal thickness of 20 mm, and a discard thickness of 20 mm. The center hole diameter measures 96.3 mm, and it features 5 stud/lug holes with a smooth surface type. This rotor is a vented type, further aiding in heat management.
