I agree with the general suspension comments - a little more soft rear made a lot of difference planting the tire through the turn rather than just rolling off the outside edge from the weight bias pushing past the limit of the rubber. Tire selection will also make a big change in how the car handles through these turns (literally every driver last year saying I needed the Hoosier investment instead of R888Rs). There is also something to say about having to adjust multiple items to get the feel you want with your driving style.
I think the main focus for any driver starting out should be consistency before major change. You may gain a few tenths in pure confidence when making a change on one run, and then be worse than when you started 2 runs later. When you do change, also go big to see what that difference results in for you. Many of us aren't good enough with weekend cars to recognize 3 clicks from soft on a shock vs 4, but will start to feel 4 vs 10. AutoX is great for this since the speed is relatively low, and hazards are limited. Maybe not evaluate over only one run either: it may be dedicating a whole event to one setting and seeing how it feels after 5 or 6 runs.
