Will this fit with my factory fog light cutouts?

This bumper comes unpainted, so you'll verify fog light hole alignment during fitment. If your OEM bumper had fog light openings, reference those locations on the new panel. Minor adjustment at the cutout is common with FRP pieces — plan for a dry fit before final installation.

Are there bumper sensor holes drilled already?

This is a clean FRP cover without pre-drilled sensor holes. If your vehicle originally had parking sensors or radar cutouts, you'll need to mark and drill those holes yourself after dry-fitting the bumper. Reference your OEM bumper location as a template.

Will this work with my lower valance and side diffuser setup?

This bumper cover replaces the front fascia only. Compatibility with aftermarket lower valances or diffusers depends on their design and fitment points. Dry-fit the bumper first to verify clearance with any existing lower body panels before committing to fasteners.
