It seems we are going further down another road with our mutual interests.It is hard for many to see any correlation of the tweaking of a suspension system on a car with the construction of a lift out tray on a tool box, but in many of my experiences I often associate very dissimilar items to things I may be working on at the time.
I agree the trailing parallel bar suspension that Dr Ferdinand Porsche developed was very low maintenance and about as close to a trouble free system ever for the time.
The way I made my tweaks to it though, made it several times more efficient for a short circle track with very short straightaways, by skewing the the whole assembly then twisting the bars in and out as previously mentioned I was able to take advantage of the natural castor changes that happen when the spindle moves up and down to cause a change in the camber. In effect I destroyed the original relative geometry of DR Porsche's design intentions. completely ruining it for use on a paved road.
Nearing the end of our 2nd season I grew bored with the whole scene. Our car had been protested numerous times although never faulted it became ever more expensive to prove the protests false.
The very last heat of the last race of the season our little 1200 had 2nd from pole in the 1600 unlimited class. Dave really stood on it through the first 3 laps then just as he was about to lap the 2nd place car in lap 4, he high sided off turn 2. after 3 end overs and 2 barrel rolls he somehow managed to re enter the track in the short back straightaway about the time the other cars were just finishing lap 5.
18 cars started 10 finished and he crossed in 5th place. No money not even the lead car money for the first 3 laps because of the 5th place flag. I pulled the engine then installed it in my 63 bug to drive for my deros vehicle after I shipped my Dodge pickup back, we sold the race car to the team at Merrell Barracks
