Will this interfere with my trunk seal or bumper fitment?

The lip is designed to mount at the factory attachment points and sit flush with the lower bumper profile. Before installation, verify that your OEM bumper mounting brackets are in good condition and that the lip sits evenly across all attachment points—this ensures no interference with adjacent body panels.

Should I use adhesive or drill new holes for installation?

Factory mounting points are your anchor. Use corrosion-resistant fasteners (bolts or screws) through the existing holes; adhesive alone is not sufficient for a structural lip that handles road debris and airflow. Drilling is not required if factory points align.

How stable is this at highway speed?

Single-piece FRP construction with factory-point mounting is stable under normal highway conditions. Ground clearance and road surface angle matter—verify your ride height and suspension setup before installation, and inspect the lip periodically for any movement after initial fastening.
