I suspect your springs may be worn out.

The official "before" measurements on mine were: 1/4" gap between bump stop & axle on the right and the left side was resting on the axle. I bought a pair of used springs and new insulators and now I have 1/2" both sides. Rides smoother and corners better. Even if you keep the spacers, I wonder if you would get the same benefits with fresh springs, too.
