Russ,
I think what you're referring to here is the, so called, "Hanford device" ,
which was sort of like oversize Gurney flaps on both top and bottom of the
wing. Made for NASCAR like drafting.

Mayf--
3. Gurney Flaps (if I remember correctly) originated as a
device MANDATED
by CART to control speeds (some say to "bunch-up the field")
on some ovals.
Michigan was one. I never saw one in use, but it seems like
I remember that
they were basically a "board" turned sideways to the wind,
and their sole
purpose was to slow the cars by creating drag-- not to aid
in downforce, at
all. I also think I remember that some of the drivers liked
them because
they created such a strong slipstream that you could use the
"slingshot
effect" for passing. Some folks were saying that these
should have been
mandated for the Ft. Worth CART race ("the race that didn't
happen"). I
think that if they had been, M. Andretti might not have
"seen the elephant"
and got them to cancel the race-- notice that he's retiring
right before IRL
goes there!
And then again-- I may be remembering this about the
wickerbills and Gurney
flaps all wrong!
