Will this interfere with the trunk seal or brake light cutout?

The Sport GT lip is designed to sit cleanly above the OEM bumper fascia without overlap into brake light or trim areas. Verify your bumper's existing fitment gaps before final installation — factory tolerances can vary slightly between units.

Should I use adhesive, fasteners, or both?

This lip mounts mechanically to the bumper structure. Reference your vehicle's service manual or the installation guide included with the product to determine fastener locations and torque specs. Adhesive is optional for reinforcing seams but not required for secure mounting.

How stable is carbon fiber at highway speeds?

Real carbon fiber is rigid and resistant to flex. This lip's one-piece design minimizes vibration. Ensure all fasteners are properly tightened before highway driving, and inspect mounting points periodically — wind load will stress any loose hardware first.
