Here is a suggestion for a compromise track/street setup:
Camber: -1.25 front, -1.0 rear (almost within stock limits)
Caster: max positive, matched side to side
Toe: 0.0 to 0.1 front (out), -0.1 to -0.2 rear (in)
To improve handling at the cost of tire wear, use more negative camber in front, slight toe out in front, slight toe in rear.
