How new are they? It's possible (unlikely, but possible) they need to settle.
What about your control arm bushings...how old are they? If new, did you tighten them before the car loaded the suspension? Are they for a 94 & up, not the 87-93?
If all is correct, settled in place, may be time for lowering springs. I personally have Bullitt springs on my 88, I really like the ride height and quality...
