Will this lip interfere with my trunk seal or bumper panel gaps?

The JCSL lip is designed to integrate at the lower fascia without contacting the factory bumper structure. Before final installation, dry-fit the piece and verify clearance at the seams where the lip meets the existing bumper edge. Minor gap adjustment is normal during the install process.

Should I adhesive-bond this or drill through the existing mounting points?

This lip uses factory mounting locations on your vehicle's lower fascia. Refer to your vehicle's service manual or OEM documentation for the bolt pattern and hardware specifications. Adhesive-only installation is not recommended for front-end pieces that experience wind and road forces.

Will the FRP stay stable at highway speeds?

FRP is durable and rigid when properly secured through factory anchor points. Ensure all fasteners are tightened to your vehicle manufacturer's specification and double-check them after 100 miles of driving. Proper installation and maintenance of mounting hardware keeps the lip secure under normal driving conditions.
