As Kev is 2wd you could get away with more front camber, as the driveshafts won't be an issue. Have you got spherical bearing top mounts? Have you got compression struts or an ARB?

Could run 3° Neg on the front for hard track use.

Toe in/out is a trade between straight line stability and turn it, the more toe out you run the faster the turn in, but the car will tramline more on uneven surfaces and harder to keep straight at high speeds.
