This can cause you too turn in too early if you are not used to it, or in really high bite tracks if you turn-in too fast you can traction roll. But everywhere else on the track less ackerman makes the car feel more precise and it is really nice, especially coming onto the straight where the car can keep hugging the pipe on corner exit.

More ackerman, makes it easier to throw the car into the corner and steer from the rear as opposed to having the front do all the work.

On most indoor clay tracks I would suggest running the rear rack location, which is less ackerman. It is definitely an underated tuning option since most people obsess over shocks a little too much.
