In the parts catalogue ETK there is a "Spring Table". The springs are determined by the model and the options fitted to them. I don't know how many different springs each model has but it is more than 5 or 6 at least for the e36, in fact it could be more than 10.

I ordered M3 springs for my e36 vert and I added the options fitted to my car wen choosing the part number. The part number changed as I added or removed things like Sport seats, fully automatic roof, etc.

I would say that SE springs would sit higher than Sport. But you can get stiffer ones by adding options in the spring table.
