What mounting hole pattern does this use?

The Ribben wing is engineered to align with factory trunk lid and bracket locations. Before mounting, verify the hole locations on your trunk lid match the wing's mounting provisions. Sand and prep the surface thoroughly to ensure secure fastening.

Will this wing sit flush with my trunk lid, or does it extend beyond?

The Ribben profile adds extension along the trunk lid. Check your trunk clearance with your garage door and any rear-mounted accessories (cameras, antennas) before final installation to avoid interference.

How should I prep the FRP before painting?

Sand the entire wing surface with standard automotive-grade sandpaper to promote primer and paint adhesion. Wipe clean, mask off mounting holes, and apply primer according to your chosen product's specifications. The FRP gelcoat is UV-resistant, but primer and paint will enhance durability and finish quality.
