I ran some really crude numbers, 100 lbs in the middle of the PHB might deflect it 1/4" or so, in which case it will return to being straight after the force is removed. I can see a person making this happen with the car up on a lift, but nothing short of a freak incident with the car in motion would bend the bar and leave it bent.

The brace is fine. I didn't abuse the car. No burnouts. Autocrossed a few times. I thought that the control arms might have deflected enough to allow the PHB to smack the diff cover but there was no evidence of that.
I'm no engineer but I'm looking into how to do buckling load calculations. Anybody know what the PHB is made of?

Yes, you can. But you can do that with any PHB.... In fact any long tube will be able to move like that when a force is applied in that direction. The car doesn't apply force to a PHB in that way, but there is inherently some bending since the PHB is not always straight.
Watts links minimize that by running two shorter bars (some shorter than others), and have no flex you can measure. So if you are really hell-bent on getting rid of the possible bending in your location device--you shouldn't have a PHB at all, but a Watts link.
