This winter, i am doing a rear end swap along with replacing the old,worn out suspension components in the rear. Whenever i am driving down a steep hill or hit a pothole, the rear end seems to bottom out, or at least it sounds like it. Maybe the tires are rubbing the wheel wells when it compresses. I am sick of the worn out suspension, so i need some info on what springs and shocks i should invest in. I am looking for a real stiff rear suspension too.
