My '82 diesel Westy springs are shimmed with pieces of cutting board. I
did over-correct on the first attempt, and had to remove shims. I have
the largest amount of shim at the left rear, and a bit less at the right
rear. I have not weighed this van.
By the time you get the body to a reasonably level state, a good portion
of the already limited range of motion at the left rear is gone due to
the spring compression required. This is why Derek's proposal to use a
stiffer spring in the left rear is interesting to me. I want the body
to be level while maintaining the range of motion afforded by a
full-length spring. Am I asking too much? How different would the
spring rates have to be to cause dangerous handling? What about spring
frequency? Can they have different rates, but the same frequency? We
are nowhere near the frequency of sports car springs in the Vanagon.
