Here is a set of original Racing Dynamics Green springs for a 6 cylinder coupe or sedan. The fronts are brand new, never used; and the rears are used with unknown mileage, but as you can see in the pics they are in good condition, just a little dirty. $175 shipped obo.
Fronts part no. is 196 10 30 002
Rears part no. is 196 20 30 002
The consensus is that these springs are a little more firm and give you a bit more drop than H&R sports. As you can see in the pic below of the rears springs compared to an H&R 50406, this appears to be correct as the RDs slightly shorter and the spring diameter is slightly wider. If you do a search, you'll find pics of e30s with these springs.
Lastly, like I said, these are for coupes/sedans but they'd probably work on a vert or 4 cyl car as well, but be a little lower in the back. E90 drop hats in the front would probably balance out the stance. The pic below shows them compared to H&R and Dinan vert specific rear springs (the two blue springs).
