It looks like you've got 3/4 of the Aerokit 1. I see the side skirts, and the rear wing with the correct trunk lid (which is rare). Usually if someone adds the wing, they just disable the automatic spoiler and bolt on a wing. What is the trunk lid made of, is it metal or composite? The front bumper cover on your car is the standard Boxster S cover, that's the only Aerokit 1 piece not on the car from what I see.
Here's a picture of what the Aerokit 1 front bumper cover looks like:
