Background: Owned 2008 WRX, now own 2010 STi. Tryin to sell STi to move into a 03-04 Cobra. Would really like to learn to autocross and I know it would be best to keep the suby to do this, but how well does the stang crowd stand in autocross? I have never been to one and I am not advocating that I am anywhere knowledgable about it. What would I need to do to the stang to compete in Autocross?
