Fair enough - the figures came from SVE themselves though. Remember there are less active coils on the rear hence the higher rate as well. Those figures were for standard springs not coilovers by the way that I gave you.
Anyway, sounds like you are sorted now
Just don't get confused between people giving you rear coilover ratings as opposed to normal mounted position springs - coilover springs are a different diameter as well on rear
Just as an aside have a look at the manufacturer figures for ther various E30s ( similar sort of car to a Sierra ) in the article below and then see if you think the spring rates I gave you are still wrong
