Will this interfere with my trunk seal or bumper clips?

The BZ lip is designed to sit ahead of the bumper fascia and factory mounting zones. Once fitted and secured to the factory attachment points, there's no interference with moving clips or seals. Verify fitment to your specific bumper condition before final fastening.

Can I use adhesive instead of drilling through the bumper?

This lip mounts to factory hard points rather than the bumper face itself, so adhesive isn't the primary method. Bolt-on installation to existing factory locations is the intended approach. If you prefer adhesive supplementation after primary fastening, consult your adhesive manufacturer for compatibility with FRP and painted surfaces.

How stable is this at highway speed?

The single-piece FRP design and low-profile BZ shape maintain aerodynamic stability at highway speeds when properly secured to factory mounting points. Ensure all fasteners are tight and inspect periodically for any loosening due to vibration or road impact.
