I have a 4/z. Car gets in and through the corner pretty good but on exit the car rares up real high and just spins. Top left bar is at about 23 deg, bottom left is at 5 degrees. Lr 250, rr 300 on swing arm. Seems like anything we do we can't get the weight back to the LR. We are running the short bar under the pinion with about 5 inches of rake.
Any help would be appreciated.

Definately sounds like its over extending and then letting loose, tire grip wise.

I believe i would try to lower that frame side mount and get some of that angle out of that panhard bar. That should remove some of the "scotch" effect from it, and allow it to roll over more naturally instead of pushing / raising the LR up.

Have you thought about a RF spring change?
Perhaps a little stiffer. If the car is rolling over on the RF then this should be considered.

Lower your top 4bar link a hole or two.

Take some angle out of the short bar.
UP on the Pinion down on the frame.

We were running a 650 lf and a 700 rf all year. Last week we switched to a 700 lf and a 750 rf, it didn't seem to do a whole lot. I'll try taking some rake out of the panhard bar.
