Some great old racing shots Paul. The wing explanation is
brief, but interesting, at least to me. Regarding Colin Chapman's Lotus
wing follies I remember Jim Hall's comment to the officials, "I have
seen wheels come off too. They aren't looking to ban wheels!" I didn't
remember your use of a watts linkage to keep the struts vertical. Seems
like a good idea. Did the rubber mount washer set ups have enough
compliance to accommodate the change in "track"? Of was the suspension
travel so short that it didn't mater?

Thanks Bill. That was a great comment of Jim's.
It was a combination of the rubber washers and the 4130
triangular leaf spring.
You probably know that the stress is constant in a triangular
leaf sprint.
It was so simple and it worked so great.

As an interesting aside, Durring my racing early years I remember
SCCA SF Region F-A was being dominated by John David Briggs. Old Briggs
and Stratton money! He had a very nice car which was built by the dad of
a guy I worked with who owned Fodge Racing. Had a good wing. He lapped
the field at one regional event as I recall. Did you build his wing? Or
was that way after you had moved on? I was getting into building
motorcycle engines at the time, (900 Kawasaki's), for LeGrand Mk8 D
sports racers. Built one for an eventual national champ David Leeson.
Sadly that was when they let the 2 strokes compete on a even
displacement and the best he did with my engine was second. This was
shades of the Wankel displacement arguments and Wankel vs. piston
comparisons.

What year was that?
Paul Lamar
I think it was 1981 or thereabouts.
