Will this lip interfere with my trunk seal or bumper gaps?

No — this is a front lip that mounts to the lower bumper fascia only. It does not contact the trunk or rear components. Verify clearance with your specific bumper by comparing the mounting hole positions on the lip to your vehicle's existing fastener points before final installation.

Can I use adhesive instead of drilling new holes?

Yes. If your factory bumper already has mounting points that align with this lip, use those bolt holes. If you want to avoid fasteners altogether, a high-strength automotive adhesive (rated for FRP) works well on clean, prepped plastic. Whichever method you choose, prep the mounting surface thoroughly and allow adhesive to cure fully before driving.

How does FRP perform at highway speeds?

FRP is stable and rigid once mounted securely. The single-piece construction means no flex points. Make sure all fasteners are tight and the surface prep is clean before finish — any gaps or loose edges can vibrate at speed. A thorough installation will hold up reliably.
