Setup for 1/5 mile dirt oval with 18 degree banking

So i went to Jackson speedway my hometrack and raced my dirt oval kart and won da feature but da car during practice was dangerously loose on da outside abd i had to get fully off gas and get back on, i was running -1.5 camber RF, -0.75 camber LF, 1.5 stagger, and yeah but it was awesome on da middle and inside but i passed on exit once on da outside abd boy i was loose turning right all da way so will more camber work on da RF and LF or more weight or is it just da fact track conditions change from time to time during each race
