Rear end squat

Yesterday my daughter filmed my car's lauching and in the film you can see my car squat, lift up and then squat again. Little front raise in a 10.20 second pass.
I think I need a SS spring. Any advice?

If its squatting the springs are shot... the front is
rolling up but the springs are just rolling ...back
of the spring is pulling it down

super stocks & hangers, solid bushings, long drag shocks, frame connectors, tourqe boxes, QA1 90/10s upfront. cage as needed.

they work fine before adding trams brake ,so y must go whit higher checking load springs ,right-

thankyou
