they take a while everytime i have dropped a car with springs it takes a while. like a month to settle to the lowered height. on my aw11 i used intrax it dropped .75 inches and after about 2-3,000 miles of driving it actually dropped down to 1.7 in the rear and 1.5 in the front. plus from the looks of the pic you don't have a swap (the front end looks light) its going to take a few weeks.
