Will the front lip interfere with my trunk seal when installed?

No. The front lip mounts to the bumper fascia at the factory attachment points and sits forward of the trunk opening. Install height is determined by standard bumper alignment—verify your bumper is level before securing the lip.

Do I need to modify my brake light cutout for this lip?

The two-piece design does not encroach on the brake light housing. Measure your existing light cutout against the lip profile before final fastening to confirm clearance on your specific vehicle.

Should I adhesive-bond or drill through for added stability at speed?

These lips are engineered for factory mounting point fasteners, which provide secure hold at highway speeds. Adhesive alone is not recommended as a primary attachment method. Use fasteners at the factory points and verify all connections are tight before your first drive.
