Still an interesting and useful link because the items there in one form or another have been discussed in the forum before.

APR Vortex Generators help to guide the air flow on cars with very steep drop-off angles between the roof and the rear window. Air flow has a tendency to become turbulent as it separates from the surface of the car in this region. This turbulent air causes drag and reduces the effectiveness of a rear wing. The APR Vortex Generator helps to reduce drag and improve the effectiveness of the rear wing by delaying the air flow separation and reducing turbulence.

I've looked for those little rods which secure splitters and spoilers before (unsuccessfully), this looks to be a nice source although I've utilized small aluminum "L" angle channels in the past (cheap).

EDIT
This was a good thread on this topic, looks like some people were proposing the trunk deck extension to be a solar panel!
