Will this interfere with the trunk seal or bumper gap?

No. The SXE lip is designed to align with factory bumper geometry and does not extend beyond OEM fitment tolerances. Verify your vehicle's bumper alignment before installation to ensure proper gap consistency.

Can I use adhesive, or do I need to drill mounting holes?

This panel is compatible with both methods. Most installs use factory mounting holes and hardware secured with fasteners. If you prefer adhesive, the FRP surface accepts quality automotive-grade bonding agents — surface prep is critical either way.

Will this lip stay stable at highway speed?

Yes. FRP is rigid and resists flex; proper mounting through factory attachment points ensures stable performance in high-speed conditions. Check all fasteners before first drive and periodically thereafter to maintain integrity.
