Will this fit if my lower valance has parking sensor cutouts?

This lip is designed for the stock lower bumper profile. If your vehicle has OEM sensor holes in the valance, verify the exact cutout locations on your bumper before final installation. The lip mounts to the factory attachment points, so sensor compatibility depends on your specific bumper configuration—compare your bumper's hole pattern to the mounting surface of this piece.

What surface prep do I need before painting?

Sand and prep the surface with your preferred grit before applying primer and topcoat. The FRP arrives primed and sanded, but any dust or handling marks should be cleaned before your final finish. Use your paint system's recommended primer and paint—FRP bonds reliably to standard automotive coatings.

Does this work with an aftermarket front splitter or canards?

This bumper lip mounts to the lower factory fascia. If you're planning to add a splitter or canards, confirm that the splitter's mounting points do not interfere with the lip's attachment zones. Most aftermarket splitters install below this piece without conflict—check your splitter's fitment guide to be certain.
