Will this wing sit flush with my trunk lid, or does it extend past the body line?

The Marga design mounts at the factory mounting points and sits within the upper body profile. Check clearance with your trunk opening fully to confirm it won't interfere with how you use the trunk.

Do the factory mounting holes line up directly, or will I need to drill new holes?

This wing uses the existing factory-style mounting locations on your vehicle. Before final installation, verify your vehicle's rear panel hole pattern matches the wing's mounting feet — minor panel variation can occur between production years.

What prep work does FRP need before paint?

Sand the surface with appropriate grit to promote adhesion and remove any surface inconsistencies, then clean thoroughly before applying your chosen base coat and clear. Your paint supplier can recommend the specific grit and primer for your setup.
