Will this interfere with my trunk seal or undercarriage components?

The lip design sits below the bumper line. Before final fastening, test fitment with your specific bumper configuration and ensure clearance from any existing aerodynamic components or protective trim.

Does this include mounting hardware?

The lip ships as a bare panel. Hardware fastening will depend on your bumper's existing mounting structure — verify your bumper's hole locations and fastener type before installation begins.

Should I use adhesive or drill through the bumper to secure this?

Both methods work depending on your bumper material and your permanent-installation preference. Adhesive-only installs preserve the OEM bumper; drilling through anchors the lip directly to the bumper structure. Assess your bumper's construction and choose accordingly.
