Agree with the above. Changing camber back and forth between street and track is doable with adjustable plates, BUT... when you swing thru a couple of degrees, the Toe also changes (mine changed drastically). So then, you end up having to pre-track adjust the front camber AND the toe (via tie-rod turns), and for me is just too many opportunities to F-up the whole setup (ask me how I know
).
As Victor said, I have been happy with static settings of -2.6F and -1.8R with good performance on the track and good tire wear on the street. I set toe to 1/16" IN front and rear. You will get many opinions on this but I find it to be an easy compromise.
