Will this interfere with the trunk seal or undercarriage when installed?

The Streetline profile is designed with minimal extension to avoid contact with stock splash guards and undersides. Verify clearance on your specific vehicle before final mounting, as aftermarket splitters can sit slightly lower depending on suspension and wheel setup.

Should I use adhesive or drill through the fascia to secure it?

This lip uses factory mounting holes and fastener points, so drilling is not required. Adhesive alone is not recommended — use the provided factory attachment method to ensure stability at highway speeds and prevent separation over time.

How should I prep the FRP before painting?

Sand the surface with appropriate automotive grit to promote paint adhesion, then clean thoroughly to remove dust and contaminants. Apply your chosen primer and topcoat per manufacturer specifications. Proper prep ensures a clean, durable finish.
