• Compatible with Hyundai vehicles including Elantra, Sonata, and Tiburon
• Fits Mitsubishi models like Expo, Expo LRV, Galant, Lancer, Sigma, and Space Star

This rotor is ideal for replacing worn or damaged disc brake rotors on these vehicles, restoring braking efficiency and safety.

Common Issues Addressed by This Rotor

• Brake rotor corrosion and rust buildup
• Uneven rotor wear causing brake pulsation
• Reduced braking performance due to heat fade
• Warped or damaged rotors leading to noise and vibration
• Rotors below minimum thickness affecting safety

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.882 inches (22.4 mm) before installation. Clean the hub surface thoroughly to prevent uneven mounting. Use proper torque specifications on the 4 mounting lug holes (0.5 inch diameter) to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s braking system. The floating disc mounting design requires careful alignment during installation to maintain proper rotor function.
