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

The lip mounts to the front fascia and does not extend into the undercarriage or trunk line. Verify clearance with your bumper's geometry before drilling or fastening to avoid contact with splash guards or existing brackets.

Can I adhesive-bond this lip, or do I need to drill through the bumper?

FRP lips can be installed adhesive-only or with fasteners through the factory mounting holes — your choice based on preference. Adhesive requires clean, dry surface prep; fastener installs offer adjustability before final curing. Either method works with proper surface conditioning.

How stable is FRP at highway speeds?

FRP is designed for street-use aerodynamic panels and remains stable when properly secured. Ensure all fasteners are tight and adhesive (if used) has fully cured before highway driving. Inspect mounting points regularly after the first few weeks of use.
