I followed your explanation until the Bottom line, which (in my humble opinion) is off and doesn't follow from the rest. You had a handling problem, and the sway bar solved it pretty easily. Bonus point, now you have the adjustability for other tracks where exit speed from an off-camber corner is way less critical.

In the costs thread, you had your running costs at roughly $800 / track-hour. $400 in labor is ... half an hour of track time. Or one (1) track tire. Or repainting half a body panel after a ding in a parking lot. On a car that's so heavy on consumables usage, that's next to nothing for the improved handling.

(Though to be fair, I'd be surprised if a bigger front swaybar only generated a better-balanced car overall. I'm sure it solved that particular corner problem. But I've ran my car in a very similar config to yours for quite a while, and its defining handling characteristic over several tracks was corner entry understeer, to the point of really needing the brakes to get it turned. A bigger front bar is the opposite direction of how I'd try to balance it.)
