Pics and year would help but it's probably what chris said. The toe adjuster on the front of the trailing arm. Also make sure the control arms aren't hitting the trailing arm itself or the unibody.
When we hacked mine I had the same problem and I found that the rear trailing arm was binding on the side of the pivot point. The trailing arms have rubber bushing and i bet they are wore out and causing them to bind on the side. Just pull the trailing arms and grind the side thats binding and notch out were they mount to your ride. Its a bitch but it will work.
if you were refering to my civic my body kit is still bout 2 inches off the ground in back and bout 4 in the front, it pisses me off, i get it lower someday soon!
