Think it's -1.5° all around, maybe -1° in the front.
If you change something, try at first the inner hole in the rear shock tower, then if it's not enough increase toe-in.
And check your rear diff!
Someone had issues with an unstable car because diff was too loose.
I think it should be possible to get the car settled without changing springs and oil. These are just for faster laps if car is running
I also tried a stiffer anti-rollbar, made the car really easy to drive but didn't have enough turn for my liking.
Also the flex is really different with the other topdeck. Somebody had a cxL there and we couldn't get it running properly on that day, so i don't know if things work the same way on the other car.
