Once in place, the mounting holes are drilled.
Here is the deck with the mounting holes drilled.
Next, a hole saw is used to enlarge the holes in the bottom of the deck so the wing mounting hardware can be tightened.
The carbon wing mount/the rear spoiler assembly is held in with bolts and two-sided tape. There the tape backing is removed.
The spoiler is attached to the deck lid taking care that the mounting holes line up.
Next, the mounting bolts are installed and tightened.
