Corey I would be getting to the bottom of the bracket breakage. Unless it is common on proteges. Even still I wouldn't think it is that common that it would happen every other time you autocross. That would be rediculous!
With a big sway bar, it's not uncommon. Lube lube lube. The bushing binds up and pops the bracket.
