Will this wing cause trunk lid interference when closing?

No — the N-1 profile is designed to clear the trunk without bind. Height and cant are engineered to allow full lid closure without modification.

Does this wing mount to the factory trunk lid hole pattern?

Yes. The wing uses existing OEM mounting points on the trunk lid, so no drilling or bracket fabrication is required.

What hardware is included to mount this wing?

Only the wing assembly ships in the box. You'll need to source fasteners separately to match your preferred mounting method and torque spec.
