Will this interfere with the trunk seal when the lip extends forward?

The K1 design sits below the bumper line and does not contact the trunk area. Before final installation, check clearance between the lip edge and your bumper body to ensure a clean fit with your vehicle's specific bumper geometry.

Can I install this with adhesive, or do I need to drill holes?

This front lip is designed for bolt-on installation using factory or existing mounting holes on your bumper. Drilling into the bumper is not required. Confirm your bumper's mounting points before beginning installation.

How stable will this be at highway speeds?

FRP is rigid enough to hold its shape under normal driving conditions. Ensure all fasteners are tight and that the lip is fully seated against the bumper before driving. Double-check that no gaps exist between the lip and the bumper that could create lift or vibration.
