Hi Justin,
I put the numbers from the Baja Bug book into the Rennlist formula.
d = bar diameter = 22mm = 0.866in (beetle stock size)
L= torsion bar length = 21.75in (effective length = 20.75in)
A = arm length = 16.5in (torsion bar centre to wheel centre)
The result is 116lb/in
According to the formula from the Baja Bug book, the force to change 1 degree is 35.6lb.
To move 1 inch of the suspension, the torsion bar will be preloaded approximately 3.4 degree. Therefore lb/in is
35.6lb/degree x 3.4degree/in = 121lb/in
Looks like the two formulas are consistent .
Hope that this is not too complicated to read.
Tim
