You basically use ackerman to balance turn-in and corner exit steering.
If the car turns in too much and snatches and then pushes on corner exit use more akerman.
If the car is pushing on entry to a corner and spins on the way out or a corner use less ackerman.
Best overall setup tip i can give is that every little bit helps so if you can shave a few grams off do it. If your bearings need lobe then do them. Check camber after every meeting and that they haven't been knocked off by that half a degree in a shunt, check your droop setting haven't been knocked out. If you have any slack in the bearings, ball joints, suspension arms replace them.
All simple little things but they all add up. I would say i spend at least 4 hours on my car checking everything is just right and clean after every meet.
