The actual rate you get at the wheel from a torsion bar depends on how long your lower control arm is (B/E different to A) and how wide your wheels/tires are.
Are you sure about this? I had always thought that, because the torsion bar is directly connected to the lower control arm inner pivot, the spring rate is the same as the wheel rate, regardless of the length of the LCA or the wheel offset - in contrast to any coil spring setup which necessarily has to be mounted somewhere between the control arm outer pivot and inner pivot and so only a percentage of the spring rate would act on the wheel, the actual amount depending on the length of the control arm and where on the arm the spring is attached (and in which case, the wheel offset would move the outer pivot and so affect the ratios and the percentage of the spring rate acting on the wheel).
Of course, I've been wrong before. . . .

I am not very good at explaining things so sorry if that sounds patronizing or is even more confusing.
Not patronizing at all, and your explanation sounds reasonable to me. Thanks for responding.

Did you decide on a leaf yet? Anything installed? How does it handle

just a few notes from my setup with 1" t-bars stock suspension, rebuilt, new rubber bushings (when I bought the car) and no-name shocks. Stock 318 leaf springs. Upgraded 1" bars, 1 1/8" front sway bar, 12" rotors, SG, and 245/45 17 tires. Fiberglass hood (weight reduction) Car handles MUCH more modern, but there are shortcomings when driven more aggressive than street. On the street its an absolute pleasure to drive. I plan on upgrading to XHD leafs soon w/ no sway bar. The rear leafs are soft. and would be very balanced at that stage. The bars are not too much for the shocks. In an agressive situation, right now, the street tires are the weak link. I'm remedying that. Further development for this car will go beyond 1" t-bars, but overall, for a street car they are great. Some taller sidewall tires (15") and even the potholes won't annoy you.
