Will this interfere with my factory trunk seal or undercarriage components?

The lip mounts to your existing bumper structure and does not extend into areas where trunk seals or undercarriage parts operate. Verify mounting hole alignment with your bumper before installation to confirm fitment with any existing trim or sensors.

Should I use adhesive or drill through the bumper to secure this?

FRP lips are typically bolted through factory mounting points on your bumper. Verify your bumper's existing hole pattern before deciding on your fastening method. Adhesive alone is not recommended for high-stress areas; hardware mounting is the standard approach.

Will FRP remain stable at highway speeds?

FRP lip panels are engineered for street use and highway speeds when properly secured to the bumper using correct fastener torque values. Refer to your vehicle's service manual for fastener specifications. Ensure all mounting points are tight before driving.
