Will this interfere with my trunk seal or undercarriage components?

The Saikyo lip is designed to clear factory undercarriage geometry. Before installation, visually confirm alignment with your vehicle's existing bumper assembly and any underbody panels. If your OEM bumper has been modified or replaced, verify clearance independently.

Can I use adhesive, or do I need to drill through the bumper?

This lip is engineered for bolt-on installation at factory mounting points — no drilling or permanent fastening to the bumper itself. Adhesive alone is not recommended for this application; use mechanical fasteners at the designed attachment locations to maintain stability at speed.

How stable is this at highway speeds?

The single-piece FRP construction and direct bolt-on design provide solid rigidity once fastened. Proper torqueing of all fasteners to your vehicle's service specifications ensures the lip remains secure under normal driving conditions, including highway use.
