Thanks for the clarification Tom. Great spreadsheet. It would appear that once the physical characteristics of the suspension are inserted into the spreadsheet, I then manipulate the "Nominal" spring rate value until I achieve the desired wheel rate value?
Leon,
I replaced the previously fabricated tube arms with off-the-shelf parts from one of many suppliers of dirt track supplies. Its swedged (or swagged depending on who says it) .090 wall, 1" (1.25" is available in almost all the same lengths) diameter tube that has the knurling and plating on them as purchased. After seeing remnants (photos) of the latest GT40 (I'm embarrased to say I can't recall this well-known member's name) crash on the track, and the bent control arms, I decided I'd rather have a control arm that may bend rather than super-duper 1.25" .125" wall) arms that may spear me in the back because they didn't deform on an impact.
