Will this lip interfere with my trunk seal or rear bumper fitment?

No — this is a front lip that mounts to the lower front fascia only. Verify clearance between the lip edge and your front wheel well to ensure proper fitment during installation.

Can I use adhesive instead of drilling through the bumper?

FRP lips are typically mounted using factory mounting points or fasteners through the bumper beam. Adhesive alone is not recommended for sustained highway use. Consult your installation guide or OEM mounting diagram to confirm the correct fastening method for your setup.

Will this lip remain stable at highway speeds?

Yes — as long as fasteners are properly torqued and the mounting surface is clean and dry before installation. FRP is rigid enough for road use when secured correctly. Check all fasteners periodically to maintain fit.
