For street use, 7 dg is fine. Dial in a little more for a more positive return to center. On the track I believe 22 is required. You will need to play with it a bit to find where it is comfortable and doesn't want to wander.
Your local truck shop can adjust the camber.
Make sure the steering box is on the high spot for toe in. 1/8 th inch is a good starting point. A drive down a cement driveway will tell you if too much or too little. When right, there will be no marks or a even mark. Darker on the outside is to much. On the inside , to little.
For street use, stabilizers are highly recommended. The high center of gravity makes them (gassers) a handful when cornering.
