There were pending lawsuits back a couple years ago because the rear suspension, if given the right series of inputs would infact JACK the car up with some force. Brad Lockhart, I believe was his name was the name of a racer who flipped a focus and ended up having some minor neck injuries. This is all back at least 3 years, so I don't recall all the specifics.

It's nothing against how well the cars handle. E30 BMWs handle quite well, as to Foci'....but they also seem to be a bit more prevelent in terms of cars that have flipped.

And again...it's not something I'd worry myself about. You're still something like 10 times more likely to have an accident on public roads than at an autocross. We hear of an autocross flip incident once every year maybe?!? That's with hundreds of clubs, running hundreds of events all over the country. I think it's a pretty damn safe sport, all things being considered.
