Taking off the shock nuts is way easier, especially with an impact wrench. I've done both. I had at least 5 coils, and still had to have the coils in bind. I have an S600 coupe, with one of the heavier duty springs, so that may make a difference.Next time, just disconnect the sway bar at the control arm and you'll have the needed extra travel. It's suggested to position the plates with 5 coils in-between.
