• Helps reduce brake fade during heavy braking or towing
• Improves heat dissipation to prevent rotor warping
• Minimizes brake dust and debris buildup on the rotor surface
• Addresses corrosion issues with rust-resistant coating

Installation Notes and Tips

Ensure the rotor is installed with the directional side facing outward as indicated by the drilled and slotted pattern. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt pattern and 114.3 mm bolt circle diameter. Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 32 mm and is above the discard thickness of 30.5 mm. Proper torque specifications should be followed to avoid rotor damage or uneven wear.

Quality Assurance
