Camber has gone positive

It's strange that it's both side at the same time if it's something broken or worn out though. Sounds like the ride height was raised, or like the car didn't settle down after being jacked up and then put back on the ground. But if you've driven it that shouldn't be the case, same for if the torsion bar adjusters haven't been changed.

Was there any "event" that brought this on? Pothole, curb, Duke's of Hazzard style river crossing?

For it to have happened without any changes suggests something broken or loose, but like I said its weird that it would happen on both sides at the same time without some kind of event.
