Does this bumper accommodate OEM fog lights or sensor cutouts?

This bumper ships as a solid cover. If your vehicle runs factory fog lights or parking sensors, you'll need to carefully mark and drill matching holes before installing. Reference your OEM bumper cutout positions as your template.

Will this work with my stock bumper assembly, or do I need to replace the entire setup?

This is a cover piece designed to be part of the complete wide body kit. It's engineered to pair with matching front and side elements for proper alignment and finish. Installing it standalone will leave gaps and fitment issues. Plan to integrate it into the full wide body system.

What prep work should I do before painting?

Sand the surface with appropriate grit to scuff it smooth, then wipe clean of dust before applying your chosen primer and color coats. Your paint supplier's prep guide will specify the exact grit and primer type for FRP.
