you should get some separation, but it really looks like you need more control. At a minimum some Rancho/Calvert SA shocks, or even some DA units to help control the rear. It seems as if the car jumps up unloading the tire...

It looks like you are running drag radials? Radials need very good prep and either dead hook or go up in smoke. Bias plies are more forgiving for poor track prep and/or poor chassis tune-up
