Will this wing use the factory mounting hole pattern?

Yes. The wing is engineered to align with OEM fastener locations, so you can bolt directly to existing trunk lid or deck points without drilling new holes or modifying the panel.

Does this wing sit flush to the trunk lid, or will there be gap?

The wing mounts at the factory attachment points on the rear panel. Before installation, verify your trunk lid is straight and free of dents—any panel warping will affect fitment. Sand any paint runs or debris from the mounting surface to ensure clean contact.

What should I do before painting?

Sand and prep the surface per your paint supplier's recommendations. Wipe down with a tack cloth to remove dust, then apply your chosen primer and color system. Follow the paint manufacturer's cure time before handling or installation.
