Dirt Oval with a jump? Odd.
Never set up for that before. I would probably start with my regular off road race set up since a jump is involved.
With no jump you can set up to turn left only & be OK, but with a jump you want it to launch & land smooth so you need equality left to right.
Try heavy oil in the shocks, 80-90 in the front and 60 in the rear to start. Try that, then adjust from there.
