If it's corner exit that's the problem, rear droop shouldn't make a difference since the rear will be under compression. I would adjust your front droop to allow more down travel. I word it this way because more/less droop is often misinterpreted.
This should help the rear retain traction exiting the corner.
What rear diff are you using? It's possible a looser rear may help. What front diff? It may be helpful if you could provide other info. such as camber, tow, etc.
I assume this is on both left and right handed corners?
