Will this work with my factory fog light holes?

This bumper is designed around JDM proportions, which may have different fog hole positioning than OEM. Measure your existing fog light cutout diameter and location before ordering, then compare against this bumper's design. You can drill custom holes if needed, but verify placement first to avoid compromise.

Do I need to drill new sensor holes for my bumper sensors?

If your vehicle has factory parking sensors in the bumper, reference your OEM bumper hole locations and mark them on this panel before final installation. FRP drills cleanly with a standard bit — just use a backing board to prevent cracking. Mark twice, drill once.

How should I prepare this for paint?

Sand the surface lightly to scuff it and improve adhesion, then clean thoroughly. The panel arrives ready for epoxy primer and your topcoat. Follow your paint system's prep steps — FRP takes finishes well when the surface is clean and properly abraded.
