Does this spoiler work as a standalone piece or does it require the full wide body kit?

This is engineered as part of the AF-1 wide body package. Panel gaps and alignment are designed around the complete kit, so installation as a standalone item will require custom fitting.

Will this interfere with trunk operation or cargo access?

The AF-1 spoiler is designed to mount on the lid itself, so trunk opening and closing operate normally. Verify clearance with any aftermarket cargo carriers or roof-mounted equipment before final installation.

What prep and finishing work do I need to do before installation?

Sand the mounting surface and the spoiler base to ensure clean contact. The FRP panel itself requires sanding and primer before paint application. Allow time for surface prep — a quality finish starts before the spoiler goes on.
