No expert here, slowed vids down to see and I would try a little preload into the left bar to stop it going left.... loosen rear shock extension till it hooks and stays hooked is what they say but I would try and stiffen them up 1 at a time as its hurting that yre or go up on pressure......and try 8 on fronts, not easy,..........we found as much as 16psi best on our 3800lb RR with 720ftlbs on the hit with a Hoosier 10x29 small tyre with c/tracs/monos. Also 880hp/3225lbs you'd be running 8.90's@149-150, and turning near 8k rpm@the stripe w/'88's/32's. And as you say perhaps somewhat less aggressive on the hit.
