• Addresses rotor corrosion and rust issues with full coating protection
• Improves braking consistency by maintaining smooth rotor surface
• Prevents premature rotor failure due to environmental exposure
• Compatible upgrade for maintaining factory braking performance

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 0.425 inches (10.8 mm). The discard thickness of 0.354 inches (9.0 mm) should not be exceeded to maintain safe braking. Clean the hub surface before mounting the rotor to ensure proper fitment. Use the floating disc mounting design to allow for thermal expansion during operation. Verify the 5-lug bolt pattern and mounting bolt hole circle diameter of 4.5 inches (114.3 mm) matches the vehicle specifications.
