Will this interfere with the factory air dam or trunk seals?

The three-piece design maintains OEM-compatible geometry at the seam points. Verify your bumper's existing air inlet configuration before final assembly to ensure no obstruction to airflow pathways.

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

Both methods work with FRP. Adhesive alone provides adequate hold for street driving; drilling through the factory bumper mounting bosses offers additional security. Your choice depends on whether you want permanent or reversible installation.

How does FRP stability hold up at highway speeds?

FRP's rigid composition resists flex and vibration under sustained load. The three-piece segmentation may require careful sealing at panel joints to prevent wind noise — use flexible sealant or gasket tape at the seams during installation.
