Will this interfere with my trunk seal or bumper latch when installed?

No. The front lip mounts to the lower edge of your bumper and does not contact the trunk seal or latch mechanism. Verify clear space between the lip's edges and any adjacent trim before final fitment.

Can I install this with adhesive instead of drilling?

This lip is designed for bolt-on installation using factory mounting points. Adhesive-only mounting is not recommended for a front bumper component that experiences wind pressure and road vibration at speed. Drilling into existing holes maintains structural integrity and longevity.

How stable is FRP at highway speeds, or will it flex or rattle?

FRP is rigid enough to hold its shape under normal highway driving. Proper torque on all fasteners and full contact along the mounting surface will eliminate movement. Check tightness after the first week of driving to confirm all bolts remain seated.
