That's why most plates have decent tick marks so you can adjust them back and forth without messing too much up. As long as you realize the toe issues like Jerry said, you'll be fine. Get a good starting point alignment for daily driving, adjust at the track, adjust back to the dd settings.
Lots of people do this. It keeps you from running crazy negative camber on a daily basis. Also, lots of good camber plate threads in the brake and suspension forum.
