Depending on how much camber you are adding, you *can* set it up so that when you move the struts in towards the center for the track day, you get just the perfect toe for the track too (zero toe). Slap them back for the street settings and you have toe-in for the street which helps make the car more 'driveable' in every day situations. Take some time with a set of Longacre toe plates and your iPhone smartlevel app and you can find a happy medium.
