Caster is a bit hard to understand for sure. My take away on Jim's problem is he feels a lack of stability at higher speeds - perhaps the car feels like it wants to wander from side to side. If that is the case then "negative" caster will only worsen that condition. It may be best to google caster settings and try to get a better understanding of what the effects of positive caster versus negative caster are. From my understanding if you want your wheels to self center and have more stability then you would want to add "positive" caster.

“Aligning torque as the result of positive caster settings produces a self - centering effect which wants to return the steered wheels back to their neutral position”

Here is a good resource:
