Ackerman is an important adjustment but it's a fine adjustment. I usually don't mess with Ackerman unless I'm totally dialed and looking for some refinement. But when adapting to different tracks, springs, oils, roll center, wheelbase are my main adjustments to get dialed in.
At this point, it's set it and forget it. Even if the Ackerman isn't in the most optimized positions for each track, I bet this cars will still make great/competitive lap times in capable hands.
