Will this wing maintain stability at highway speeds?

Yes. The Legera profile is engineered for balanced downforce without creating lift or flutter. Once secured to the factory mounting points, the FRP construction resists vibration and maintains rigidity across normal driving conditions.

Does the wing interfere with the trunk lid when opening?

No. The Legera design mounts within the factory spoiler area and clears the trunk opening. Verify clearance by dry-fitting before final fastening, especially if your vehicle has aftermarket trim or a lowered suspension.

What prep work is needed before painting?

Sand the primer surface with medium-grit sandpaper to ensure paint adhesion, then wipe clean. Apply your chosen basecoat and clear coat per manufacturer specs. The FRP surface bonds well with standard automotive finishes when properly prepped.
