Product Line Details: Element3; Coated Rotor

The Element3; Coated Rotor line by Raybestos focuses on corrosion resistance and consistent braking performance. The coating helps protect the rotor surface from rust and environmental wear, extending the service life of the rotor. This product line is designed to meet or exceed OEM specifications, making it suitable for Subaru vehicles requiring precise rotor dimensions and reliable heat dissipation.

Technical Specifications and Features

This disc brake rotor features a vented design that improves heat dissipation during braking, reducing the risk of brake fade under demanding conditions. The drum-in-hat configuration integrates a parking brake drum within the rotor, providing a compact and efficient braking solution. With a 5-bolt mounting pattern and a 4.5-inch bolt circle diameter, the rotor ensures secure attachment to the hub assembly. The nominal thickness of 0.704 inches (17.9 mm) and discard thickness of 0.630 inches (16.0 mm) define the usable rotor thickness range, critical for maintaining braking efficiency and safety.

Applications and Problem Solving

• Replacement for worn or warped rotors on Subaru WRX and Tribeca models
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps restore proper braking performance and pedal feel
• Prevents rust and corrosion-related rotor degradation
• Supports parking brake functionality with integrated drum-in-hat design

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is within the nominal range and above the discard thickness to maintain safety standards. Use proper torque specifications for the 5 mounting bolts to avoid rotor warping. It is recommended to replace brake pads simultaneously to optimize braking performance. Check compatibility with your specific Subaru model year and trim to confirm fitment.
