Technical Details and Construction

The DuraGo BR900490 rotor is made from full cast iron, a material known for its excellent thermal conductivity and wear resistance. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade. This rotor does not include an ABS tone ring and features a non-directional braking surface, allowing installation on either side of the vehicle without concern for rotor orientation. The conventional rotor construction ensures compatibility with Subaru Impreza and WRX STI brake systems that use standard disc brakes.

Compatible Vehicles and Applications

This disc brake rotor is specifically designed for Subaru Impreza and WRX STI models, ensuring proper fitment and performance. The part number BR900490 corresponds to rotors that meet OEM specifications for these vehicles, making it suitable for replacement or maintenance of the braking system.

• Restores braking efficiency on Subaru Impreza and WRX STI
• Addresses rotor wear and thickness below discard limits
• Reduces brake noise and vibration caused by warped rotors
• Improves heat dissipation to prevent brake fade during aggressive driving
• Replaces damaged or scored rotors to maintain safe stopping power

Installation Notes and Tips

When installing the DuraGo BR900490 rotor, ensure the mounting surface and hub are clean and free of rust or debris to promote proper seating. Verify the rotor thickness before installation; replace if below the discard thickness of 1.1 inches (28 mm). Since this rotor is non-directional, it can be installed on either side of the vehicle. Use the correct torque specifications for the mounting bolts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
