Will this lip interfere with my trunk seal or lower bumper panel?

No. The lip is designed to mount flush with factory attachment points and sits forward of the hood line, so it won't interfere with the rear trunk assembly or bumper fitment. Verify clearance with your specific vehicle's lower fascia before final installation.

Should I use adhesive or drill through the factory mounting points?

This lip uses existing factory mounting locations, so drilling is not necessary. Use the original fastener holes and hardware to secure the panel. If your mounting points are damaged or missing, you may need to consult your vehicle's service manual or a shop for reinforcement options before installation.

How does FRP hold up at highway speeds?

FRP is engineered for road vibration and wind load. The single-piece construction provides excellent stability when properly mounted to factory points. Road salt and UV exposure over time may require occasional cleaning and a protective coat of wax, but the material resists cracking and maintains its shape in normal driving conditions.
