Will this lip interfere with my trunk seal or door gaps?

No. The Lazer profile is engineered to sit cleanly at the bumper perimeter without creating contact points elsewhere. Verify clearance to your front fender and hood edges before final fitment — minor gaps are normal and seal naturally once mounted.

Can I install this with adhesive, or does it require drilling?

Both methods work. Adhesive (urethane-based automotive trim adhesive) is the cleanest install with no fastener holes visible. Drilling through the mounting flange gives you mechanical backup if you prefer. Sand the adhesive surface lightly and allow full cure time per your adhesive product's instructions before driving.

How stable is FRP at highway speeds?

FRP is rigid enough for street use and handles sustained highway driving without flex or vibration when properly secured. The single-piece design eliminates panel separation issues. Ensure all mounting points are fully fastened or bonded — any loose section will vibrate and can damage the finish.
