I installed my Eibach prokit and FRPP caster camber plates, my question is after i installed the springs and lowered the car off the jack my front dropped 1" right away and the rear a 1/2". after driving about 40 miles the front went down another 1/4" to 1 1/4" total . and the rear is still only a 1/2" lower than stock, WTF? will the rear take longer to drop because there is no weight in the back? I installed the springs exactly as the instructions show. How long should i wait to go for and alignment?
