What does your lowering parts consist of? From personal experience and what I've seen on here, stock hangers and a flip kit work the best with caltracs. You could even throw a 1" lift shackle on there if you dont want a 6" drop on the rear of the truck. I think if you did that and lightened up the front end a little you will see some improvement in your 60'

 

Fwiw, I switched from some djm drop shocks to some rancho 9 way adjustable(Calvert racing) and they seem to carry the front end much better(haven't been to the track with these yet)

 

you can clearly see in the slo-mo video that you launch, the tires grab the track and pull up the front and then as soon as the caltracs do their thing the tires spin and the front end drops... idk if you need more or less preload in the caltracs but they are what needs adjusting! they just "hit" so hard that the *** end of your truck shoots up and takes the load off the tires.
