Will this lip interfere with my trunk seal or undercarriage?

The front lip mounts at the factory points and sits flush with the lower fascia. Before installation, verify clearance between the lip edge and your bumper undertray. If your vehicle has had previous modifications to the front bumper area, physically check fit before final fastening.

Should I use adhesive, fasteners, or drill through the bumper?

This lip is designed for bolt-on installation using factory mounting points — no drilling required. Use OEM fasteners or equivalent hardware that matches the hole pattern. Adhesive alone is not recommended for long-term durability at the front bumper.

How stable is this at highway speed?

FRP front lips are naturally rigid when properly fastened at all mounting points. Ensure all fasteners are snug and double-check them after your first few drives to prevent any vibration or movement caused by road turbulence.
