I modified my swaybars about 12,000 miles ago and it has made a substantial difference in the side to side motion. I have much less lean in sharp turns and the side wind makes less movement. large trucks passing at a great speed still moves you but a lot less.
It was worth the time to change to holes.
I also will keep my eyes open if this mod wears the bushing out more over time. Presently no big issues.
