Will this bumper cover fit over my factory fog light cutouts?

This is designed as a complete replacement bumper assembly. If your vehicle has existing fog light openings, verify the 1M-look cutout locations align with your setup before final installation — the lower grille profile may differ from OEM. Reference your vehicle's bumper hole spacing if you plan to retain factory lights.

Can I use this on a lower valance or does it sit higher than the factory bumper?

The 1M styling includes an integrated lower section that replaces the OEM valance area. Installation requires a clean removal of the factory bumper and trim. Measure your existing mounting points and compare them to the new panel's attachment holes to confirm fitment for your setup.

Should I sand and prime this before painting?

Yes. Sand the surface with appropriate grit to promote paint adhesion, then apply your chosen primer and topcoat system. Surface prep is critical for a professional finish — follow your paint manufacturer's prep guidelines for FRP panels.
