I would agree that this is the first thing I would check. However, I think you have that backwards. Increased toe-in will help straight line stability in a rear wheel drive car. Before I went for my alignment, my car was also very twitchy. Turns out my eye ball alignment included slight toe out (it was only for go kart mode anyway)
