Does this bumper have existing holes for fog lights or parking sensors?

This bumper ships as a solid panel without pre-cut holes. If your vehicle's OEM bumper has fog light or sensor openings, you'll need to mark and cut them before installation. Reference your vehicle's original bumper hole locations to ensure proper alignment.

Can I install this without modifying my lower valance or undertray?

The GT Concept styling includes an integrated lower valance design, so existing factory undertrim may need adjustment or removal for a flush fit. Check your current bumper and undertray setup before installation to identify any trim pieces that may interfere with the new panel's profile.

What surface prep is needed before painting?

Sand the surface with appropriate grit for your chosen primer system, wipe clean, and follow your paint manufacturer's recommendations for adhesion and cure time. Proper prep ensures paint adhesion and finish quality — refer to your paint supplier's technical data sheet for exact grit and primer specifications.
