4000 Series HD Single-Piece Brake Rotor

The DBA 4000 Series HD brake rotor is engineered as a direct replacement, single-piece upgrade for drivers seeking enhanced braking performance beyond OE levels. Cast from XG-150 high carbon alloyed iron, its metallurgy is enhanced through Thermal Stability Profiling (TSP) to reliably handle the increased heat and stress of demanding braking applications. A key feature is DBA's patented Kangaroo Paw ventilation system, which utilizes 144 diamond and teardrop-shaped pillars. This leads to significant heat dissipation, minimizing brake fade, increasing braking effectiveness, and extending the service life of both pads and rotors. The 4000 Series HD variant offers a smooth, OE-style finish, making it ideal for applications where an original equipment look is desired, such as in certain controlled racing divisions. The rotor also includes Thermographic Temperature Monitoring markings, which change color at specific temperature thresholds to provide a clear indication of peak braking temperatures and help monitor rotor fatigue for warranty claims or replacement decisions. Non-friction areas are protected with paint to reduce corrosion and enhance appearance. Technical specifications for the DBA4425 include a 276mm diameter, 24mm thickness, 45mm height, and a 69mm center hole diameter, with a minimum thickness of 22.4mm and 5 wheel stud holes. It is designed for the front of vehicles such as the Mitsubishi Magna 93-ON, 1998-1999 Mitsubishi 3000GT (excluding VR-4 models), 1998-2004 Mitsubishi Diamante, and 1998-2000 Mitsubishi Eclipse. It's important to note that vehicle fitment information should be used as a guide, and users may need to measure their existing brake discs to ensure compatibility due to potential variations in factory brake packages.
