thanks for all your help. I was testing an a track with a bit more grip last weekend and the car was much better.
I cut the bladders in the shocks and didn't tightend the bottom cap that much and the shocks were much smoother and it helped the car a lot. I read cutting bladders would make the car better on jumps but it made a huge difference for me, maybe I am too stupid to build them proper with the bladders. I had rebound with the bladders, now I built them with zero rebound that helped too to make the car more stable I guess.
I dont know if its right but I changed antisquad from 1 deg to 2 deg and the car was much better for me both on rear and front. (strange but true)
The weight behind the esc helped a lot too, do you run the Losi weights? They are expensive but it seems to be better than gluing them. I will try weight behind the battery this weekend and I will go back to the 5 degree caster block. Really happy at the moment but I should try different tracks with less grip. But I tried a RB5 to compare and I like how the 22 is in rough sections and how it jumbs.
@Matt Butcher: the diff is still great
btw: I started with end point adjustment 80 % but got back to 100% very soon as the car is much better now, zero expo.
