Yes.

I've found the hardest setting to be a bit harsh for daily driving on our horrible streets, but you're right, it has done wonders for body roll. It's a good thing that you're getting some dampening at the hardest setting. You don't want it to be completely solid.

the difference in dampening is alot more in compressing the shock quickly. youll be able to move if if youre moving it slowly, but try to push with one really strong quick push. youll feel its alot stiffer than when you push it slowly. thats why they call them "shock" absorbers the spring absorbs and dampens/resists against more of the resonating type vibration. thats why after you go over a bump the car doesnt bounce up and down much.
also, the preload of the springs will affect the stiffness alot. you can only compress a spring so much until it either bottoms out or pushes back just as much as its being pushed on.

 

Or you can get some Daizen camber correction bushings, which I have for sale
