Much more stable car than it was before. I personally am going to play with tire pressures/rebound first then start raising the rear ever so slightly. That's what I'd recommend over vs changing tires around
I adjusted rebound between sessions... I was running the lowest setting up front. I added 1/4 turn up front and went from 1/4 to 1/2 in the rear. what it did was delay the push.
Spencer (multi time H2 NE champ and national champ) says I'm using up my front tires and they are going away. that its not particularly mechanical push, but I need to make mechanical adjustments to the car to make it easier on the front tires to drive fast. some things he recommended to help overall:
1. run new or known tires (he said its impossible to get a baseline without consistent tires)... he said the 225s will take longer to heat up and go out, they wont give me more grip/speed, but extend the consistency... he also said, if you keep your alignment neutral between tracks, you will no need to rotate the tires as they will heat cycle out before they wear "too weird"
2. increase the front spring rate (the car, on 3 wheels, overworks the front tires)... he said that since this setup worked well on with the B20 but not with the ITR, the extra weight of the ITR must be causing issues.
3. get to at least 0 toe in the rear OR add some toe out to help the car naturally rotate

I have a plethora of rear grip ... its a smidge tight on my restricted wheel size.... and might not help the front/rear grip balance I'm trying to strike.
I'm thoroughly in the fix the front camp. Remember what I said right after you finished the BOTE race? You were rolling over on the front pretty hard. Sylvia and I went down to the other end of the track and I could tell you were pushing bad in turns 6-9. That orange splitter is great for watching what the car is doing and figuring out what it wants.
I think you would benefit from more spring rate in the front, and we will get a more accurate toe reading next time we set it up. That was a primitive baseline.
If you want to build consistency in the car, you need fresh tires. But you also need consistency in yourself. Seat time is always important, and as far as wheel to wheel, navigating traffic is only going to come by experience.
You'll get there. It's just getting all those little pieces together to make it happen.
