Tim;
In our discussion on torsionbar rates some time ago

I noticed that your maths overdo mine greatly.
Now I found this article of Porches torsion bar rates converted to inch/lbs
http://tech.rennlist.com/911/pdf/torsionbars.PDF Maybe you can get something out of it with the information you have from the Baja Bug-book.
If you get interested on it let me know of the results.
