Does this wing use the factory roof mounting holes?

Factory mounting points vary by trim and options. Before installation, inspect your roof panel for existing holes or clips that align with the wing base. You may need to drill new mounting holes based on your vehicle's specific roof configuration. Reference the roof structure in your service manual or test-fit to confirm alignment.

Will this interfere with a trunk spoiler or rear hatch opening?

The wing attaches to the roof trailing edge. Clearance between the wing tip and any existing rear glass or hatch depends on your exact setup. Before final installation, open and close your hatch fully to confirm there is no contact. Test clearance with the wing loosely positioned first.

How should I prep the FRP surface before painting?

Sand the surface with appropriate grit to create a smooth, even base for your finish coat. Wipe down with a clean cloth to remove dust. Follow your paint manufacturer's instructions for primer application and topcoat. Proper surface prep ensures clean lines and durable color.
