Do I need to drill or modify the rear bumper to install this?

Installation mounting points vary by vehicle setup. Reference your OEM rear bumper structure and the diffuser's mounting surface before beginning work. Most installations use existing bolt holes or require minimal drilling — verify alignment with your specific bumper configuration.

What surface prep is needed before painting?

Sand and prep the FRP surface with appropriate abrasive media to ensure primer and paint adhesion. After sanding, clean thoroughly to remove dust. Apply your chosen primer and paint system per manufacturer instructions for best results.

Will this rear lip survive road debris and impacts?

FRP is impact-resistant and tougher than many aftermarket plastics, but it is not indestructible. Minor scrapes and scuffs can be sanded and repainted. Avoid dragging or high-speed contact with obstacles. Once sealed with primer and paint, the finish adds an extra layer of protection against UV and moisture exposure.
