Okay, Carl Anderson got me on that one. I said that the rear wing provides no downforce and he corrected me. The rear wing at all known speeds adds downforce equal to its mass when the car is sitting still.

On a similar note, the 22b (of which 400 were ever made) had the two-position tail wing that could be capable of inducing downforce.

Hi all,
I was always led to believe that the rear wing ( low level wing on
legacy/liberty) did NOT produce any down force. Its purpose was to
smooth the laminar air flow off the rear window and boot lid into the
slipstream behind the vehicle, thus creating less of a vortex/low
pressure area behind the vehicle, thus making it more slippery
through the air, better performance (probably imperceptable), and
better fuel economy, maybe proveable under perfect conditions, but
maybe unrealistic in real world, what with all those butterflies
flapping their wings in the Amazon Basin upsetting the world weather
patterns ---- who knows??

Woollen tails taped down the back window, across the boot lid and
across the rear of the vehicle, with and without the rear wing, will
demonstrate the point, the publication, "20th Century Performance" by
Julian Edgar, publisher of Autospeed on line auto magazine
(www.autospeed.com.au)has the pictures to demonstrate the idea.

It is much along the lines of the KAMM tails first introduced on some
european vehicle in the late 50's early 60', and since then many
subtle variations on many other autos.

my 2cents worth, be interested to hear any other theories!!!
