I've seen splines twisted and axles sheared off, but not bent flanges like this.
The flange itself doesn't bend. It bends at the base of the shaft. You have a real powerful, heavy car. If the tires bite hard enough, something has to give. Truth be told, you probably need a larger diameter shaft (ie: 40 spline). But that's a lot to change up. If you can get another set of axles to outlive the warranty, what's wrong with that?
