Speaking from personal experience from doing this exact thing on a Limited, I can tell you it made mine feel much more "stable" in corners.

Some argue that a thicker bar in the front will promote understeer, but I noticed just the opposite. With the front rock-solid, the rear seemed to loosen up a bit during aggressive turn-in. As the rear came around, you were then entering the apex and it seemed to help align the car for the exit line better. Had the oversteer been worse, I would've plowed through the corners and would have needed to lift the throttle to tuck the nose in.

In short, yes it's worth doing. I did the Dragon two years in a row... once with stock configuration, and once with the thicker bar in the front. The latter combo gave me much more confidence in the corners.
