Does this wing mount to factory trunk-lid holes or require drilling?

Verify your vehicle's OEM trunk-lid hole pattern against this wing's mounting footprint before assembly. Most installations use existing factory attachment points, but some applications may require minor hole enlargement or additional drilling. Reference your vehicle's service manual or have your installer confirm fitment on your specific assembly.

Will the wing interfere with trunk operation at full opening?

Measure the vertical clearance between your fully open trunk lid and the wing's rear profile. Motion-style wings sit higher than OEM spoilers, so overhead garage door clearance and trunk-lid swing should be verified before installation. Test the lid movement by hand during mock-up.

What prep work does FRP require before paint?

Sand the surface with appropriate grit sandpaper to create a uniform tooth, then clean away all dust. Any low spots or surface irregularities should be addressed with filler before your final primer and color coats. Let your paint supplier recommend prep steps specific to your chosen finish system.
