You'll want to stiffen your rear sway bar - a lot.

This will help prevent the inside rear tire from lifting and thus causing it to traction roll (this will also help it kick out so you can sort of drift it).

I'd also suggest P3 rockers. They help keep the truck from diving (transferring weight) too much in turns, which will help avoid traction rolling. It does not sacrifice handling in rough surfaces too much as long as you set the suspension up properly (ie, use the adjustment on the arms to lower the truck, not the pre-load).

I have most of my trucks this way - set up to just lose traction and slide rather than transfer weight and traction roll. As long as you are comfortable driving with the read end kicked out, it makes for a much more controllable vehcile, as rather than have it flip it just kind of slides out (and you can just control it to keep it going where you want it).

Just experiment with spring rates and pre-load and suspension height and you will find a happy medium. I spent about 10 hours of run time on the track tuning my G2R's suspension and I have it right where I want it. My diff unloads like crazy (and is actually toast, but I have V3 Hybrids from Mike ready to drop in). But right now I can drive it like a crazy person and unless I'm on the street, and at its limit the back end will just kick out if I'm under hard accelleration, or if I'm braking or coasting the truck will just slide as whole. All I have to do is make some steering correction and even if the truck looks like its out of control, its actually going in the direction I want it to.
