Measure out 5 to 10 mil between your thumb and finger its not much at all.
I know 2 people who bought these and had them up for sale straight away once the saw how much it actually dropped the car. 
....Yes, because they bought these springs out of ignorance - They were only going for the lowered look and not considering anything else. Like I said, these Eibach Pro's are perfect for the KoniFSD's because they smartly soften/harden according to the road surface - An ineviatble compromise which necessitates enough room to travel.
There are plenty of other springs which will achieve a lower look.
Horses for courses.
