The best thing to do for OCCASIONAL track duty is to put the negative camber at it spec limit, which is -1.0 degree. Also, try to get the + caster to the limit as well but have it even on both sides. Leave the toe at the stock setting. Performance settings may induce pulling to one side or the other but these are not harmful. On the rear suspension, same just take the - camber to the spec limit(I think is -1.5). Having the car lower may have already done that for you.
I was looking for ideas a bit more aggresive. I think I had those settings before I installed the springs, which now are probably even more aggressive after the drop. Gonna try and get an alignment appt for this weekend.
