Does this spoiler interfere with the trunk lid when opening and closing?

The Z28 profile is designed to clear the trunk swing path. Before installation, manually open and close your trunk to verify clearance at full extension. If your trunk modification or aftermarket hardware changes the hinge geometry, test fit first.

What are the mounting hole locations relative to the OEM trunk?

This panel uses the factory trunk mounting points. Reference your vehicle's OEM mounting hole pattern before drilling any new holes. If your trunk has been repaired or replaced, verify hole alignment with the donor panel.

How should I prepare the surface before painting?
