1. not sure what you're asking, but the Z32 rear suspension is basically the same as the S13/14, strut length might be different, frotn suspension is similar only at the LCA an TC rod, the Z32 uses an upper a arm that the S13/14 don't so frotn struts most likely won't transfer witout some fab work2. if you are running coil overs you can get any spring rate and free length you want from any decent supplier, just figure otu what rate and length you want and call GC ro whoever (GC is quite exensive on their coils, summit is a lot chaper but less selection)
I'm not quite sure ewhy you want to use Z32 parts? if you get a good set of coilovers they can be rebuilt and revalved to suit your needs, and of course as I already mentioned spring rates and free length si pretty much unlimited
