Will this lip interfere with the factory bumper seal or air dam?

No. This lip is designed to mount cleanly to the existing bumper structure without interference. Before installation, verify clearance with your vehicle's underside components and test fitment at low speed to confirm alignment with factory lines.

Does the clear coat need maintenance, or will it yellow over time?

The UV-protective clear coat is built to resist yellowing and oxidation. Regular washing and occasional wax application will maintain the finish. Avoid prolonged exposure to harsh chemicals or high-pressure spray near seams.

Can I drill through the carbon fiber if my vehicle's bumper has different mounting points?

Yes, carbon fiber can be drilled. Use a sharp bit and low speed to avoid cracking the weave. Seal any drilled holes with clear epoxy or touch-up resin to prevent moisture intrusion at the carbon layer. Reference your vehicle's OEM bumper hole locations to plan mounting before drilling.
