The stock spoiler is a nice piece for a wing style spoiler. Other style options are GT-Wing and Ducktail. If you remove the stock spoiler there will indeed be holes. I ended up going spoilerless and love the look. For aero, I am adding a Velox?FT86Speedfactory functional diffuser to the bottom of the car this weekend (arrives in mail today).
No suggestions for anything else cause I don't know your taste.
