Does this wing use factory mounting holes or require new drill points?

Reference your vehicle's OEM trunk lid hole locations before installation. Most wings of this style align with factory points, but verify your exact setup against the mounting face to avoid unnecessary drilling.

Will the wing stay stable at highway speed?

FRP wings are rigid and lightweight when properly mounted. Ensure all fasteners are torqued to spec per your vehicle's service manual and double-check that mounting hardware is rated for dynamic loads. A secure base keeps the wing planted.

How should I prep the surface before paint?

Sand the surface with appropriate grit to scuff the primer, wipe clean of dust, and mask off areas you don't want painted. Follow your paint system's prep steps — the primer base accepts standard automotive topcoats without additional treatment.
