Will this air dam interfere with the trunk seal or undercarriage clearance?

This is designed as a front under-bumper piece and sits forward of the trunk area, so no interference with rear seals. Before installation, verify ground clearance on your specific setup — approach angle and suspension height will determine safe fitment.

Do I need to drill through the bumper or can I use adhesive?

The mounting method depends on your preference and existing OEM hole locations. This piece is built to work with factory mounting points on sport models. Adhesive alone may not hold under highway speeds — combine it with bolt-down anchors for stability and durability.

How do I prep the FRP before painting?

Sand the surface with appropriate grit to promote paint adhesion, then wipe clean. Apply your chosen primer and topcoat per your paint system's specifications. Proper surface prep is critical for color match and long-term finish quality.
