Kas,
What is the reason for designing the spoiler to allow it to bend up and down
rather than just to remain down? Reduction of drag at lower speeds?

The last spoilers I did for the TR-6 and the GT-6 were tested several times
with various fiberglass layups so that the thickness allowed the spoiler to
bend down as the speed increased. This really controlled the nose lift, the
cooling and allowed entry speeds higher as there was no initial understeer
from the "lightness" as Bill encountered. We did a lot of the work right out
on the freeway in the late evening on a stocker paced by another car
watching the trial. It was pretty effective. Kas
