I feel like I'm getting close on car setup now and am down to fine tuning what I can on my 2022. Have Konis (front and rear w/legal perch), Karcepts bar on the 2nd softest hole, crash bolts, and am now playing with alignment. Ran an event on concrete that's similar to Lincoln's surface and we struggled with not being able to get the rear to rotate well, particularly on-throttle. Best the car felt was full rebound on the rear and minimum rebound up front, but it still wasn't where we'd really like. We could get the rear to move on lift but as soon as you're on the gas the rear would plant and it became way too easy to get into an understeer situation. Some of that is driver since we're both used to higher power RWD cars where throttle steering is easy but we think would should be able to get a least a bit of rotation on corner exit and it's just not there. On the positive side, the car was amazing on fast transitions and we had a ton of confidence with it in slaloms, offsets, etc.
Currently have just a smidge of toe in on the rear (~1/16" measured with plates) - going to back that out to zero, possibly even a touch of toe out, and and thinking about moving the front sway to the softest setting. Open to other ideas on adjustments besides just driving better
Other than setup I think we're going to need to learn to just be more patient on corner entry to work around the understeer issue and take advantage of being able to get 100% on the throttle much earlier than I could in past cars.
Edit: My codriver's run from day 2 gives some really good examples of the conditions where the car would rotate vs plow. My aggression was lacking that day so my own video isn't really helpful.
