I have a Lola T540 that has been modified first to Super V and then to
Atlantic. The wing it now sports does not look like the current single
plane wings used by FA. It looks something like this:
(ASCII leaves alot to be desired when doing graphics!!)

There are three horizontal planes labeled in this drawing as 1,2, and 3.
The plane 1 is about 10 inches from leading edge to trailing edge and is
virtualy horizontal. Plane 2 is 6.5 inches front to back and is at an
attack angle of about -20 degrees and the third plane is about 6.5 inches
front to back at an attack angle of about -45 degrees. There is a slight
gap between the planes of about 1/2" so that none of them are stalled.
My question is, "How do I adjust this wing for minimum down force? And I
hope, minimum drag."
I ran the car the first time without any aerodynamics so I could get used to
the car with no aerodynamics on it. I am now going to add the wing but I
want to start with minimum effect and graduate to more as I see what it
does. Then as the rear wing begins to force the need for it I will add the
front spoiler and the side pods.
There is no real adjustment available on the planes so I intend to add some
mounting holes so I can adjust the planes. I would just leave it as I found
it except that the PO was using it for AutoCross so I am sure that on a
track the down force on that wing will be far too much on the straight since
I will be reaching much greater speeds than he did. I would hate to arrive
at turn #1 with the front wheels in the air!
Any comments on how you would do it will be greatfully accepted.
