1999 silverado

What kind of suspension is everyone running in the front of the 1999 and up silverado. I have stock control arms and drop spindals with a 4.5" cup on top and a 1" cup on bottom. The truck does not quite lay and the negative camber is real bad when the truck is down and it is fine when the truck is at ride height. Most of the trucks i see lay on the ground and the camber is not that bad. does anyone have any suggestions!

my 2000 has mcgauhey spindles 4"lower control arms from the static drop ,like a five inchfront top cup no bottom cups on slam 72S

check to see if the control arms are hitting the frame, idont know about your year but my on my 89 the a arms hit the frame
