Unfortunately, there is no real answer to your question.
Everyone has a different driving style. Some are naturally faster than others - regardless of car set-up.
So, I would recommend the following:
1. Inflate all 4 tires to 10 PSI over recommended.
2. Set the car to a neutral alignment setting. Namely as close to ZERO as possible. This will give you an idea of what adjustments need to be made.
3. Run the AX. Determine where the car is understeering/oversteering and where it felt the most comfortable. Also, look to where you experience wheelspin.
TAKE NOTES !!!
You are not going to win this AX, but it will give you a good idea of how to set the car up for the next event.
You mentioned camber. The thing to remember is that while camber helps in corners, it is DETRIMENTAL in straights because you do not have as much contact between the tire surface and the asphalt.
So, I guess what I am trying to say is establish your baseline and make SMALL adjustments. It might take you 1/2 a season, but you will be better prepared for the last half and the next year.
Hope this helps.
