Will this interfere with my trunk seal or weatherstripping?

The AF-2 geometry is designed to sit cleanly above the trunk panel. Before final installation, test-fit the wing with the trunk open and closed to confirm clearance with your specific seals. Minor gaps between the wing root and trim are normal and do not affect function.

Should I use adhesive or drill through the trunk panel to mount this?

Mounting method depends on your preference and local expertise. FRP can support both adhesive bonding and hardware fastening. If you choose to drill, mark and pilot through the wing into the trunk panel carefully. If you prefer adhesive, ensure both surfaces are clean and scuffed before application. Reference your vehicle's service manual for any brake light cutout or wiring considerations in the trunk area.

Will this wing stay stable at highway speeds?

FRP wing construction is rigid and performs reliably once properly secured. Mounting stability depends entirely on installation quality — ensure all fastening points or adhesive coverage is complete and cured fully before driving. A properly installed AF-2 wing will not flex or rattle under normal highway conditions.
