spring rates and heights are MUCH different on all corners.
you should take into account the fact that your front springs for example are much stiffer than base model trucks. they are also shorter as well, as is the strut itself. couple that with a spacer lift and the ride and handling qualities of the truck should be simply ridiculous.
also, the rear leaf pack is of the same design as the base model trucks but are still different; the progression is much different as is the actual arch of the leaf pack. also, your bump stop is of a different design than the base model 5 lug trucks. so if you use the stock Bilstien rear shocks you'll probably over extend them, and if you use lift shocks you have the chance of bottoming out the shock.
so your calculations on lift height are way, way off.
sometimes peoples from the internets have some useful advice.
