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?
