im really leaning towards believing my rears are jdm, but if you count (starting from the base of my rear spring) the number of 360 degree turns, mine have 7 (with another 180 of a turn to the end, which isnt pictured very well, the extra 180 that is), where the pics of the rear spring that you and nhluhr posted have 6 360 degree turns (plus about an extra 90 to finish it off). mine are obviously a different product meaning there is a possibility of different spring rates. thats what is currently confusing me.
