Will this fit over my factory fog light cutouts?

Yes. Reference your vehicle's OEM bumper hole locations before final installation to verify alignment. If the fog openings differ from stock, you may need to carefully modify the cutouts to match your setup.

Does the lower valance clear my front splitter or air dam?

The Xtreme style includes a more aggressive lower design. Measure your existing front-end components and compare clearance before purchase. Custom fitment may be required if you're running a non-stock air dam or splitter.

What prep work should I do before painting?

Sand the surface with appropriate sandpaper, then clean thoroughly to remove all dust. Apply your chosen primer and paint system per the manufacturer's instructions for best adhesion and durability.
