To add even more downforce.

Dude, give it up.

That's the thing, spoilers and airdams DO NOT add downforce. They break lift by disrupting the airflow over and under the car. The only thing that actually adds downforce is an airfoil (inverted wing) as found on indy cars.

Properly designed you can get downforce just from the shape of the body. Wings will add to it, but most vehicles get some downforce of the front end and a little lift at the rear. Chrysler's ME412 prototype has a wing that it retracts at higher speeds because it's not really needed for downforce and it just adds drag that reduces top speed.
