Like many others have said, its pushing on a lot. But as you don’t know the history, I would return to the base setup and it still turns in like that then I’d move the track rods end inwards on the stub axles to give you more ackerman, as illustrated below with my little red arrow.
I’m not really seeing the knife edge hoppiness you describe, but it might feel that way if the rear is really stiff (bouncing off every imperfection in the asphalt instead of absorbing it).
