I wonder as well, what about the years of the cars? I autocross all the time, hard hard rights. My car has also been known to burn a little oil runs about a half quart low at times. BUt I have pushed it hard very very hard through right handers, even had the ass end swap with the fron end on one autocross track but I have never had a problem.
Oh well as long as they are picking up the bill!
