5k in the center seems pretty low.. I run 10 k.. 15 k if im onblue groove...
this is if your looking for more rear bite.. try this..
other than that all sounds well I would move your rear upper arm to the inner middle hole to lengthen your link.. This will make the rear of the truck more controllable by changing your roll center.. also if thats still not enough you can then run it to the outer hole at the wheel..
I run different pistons and heavier oils.. but you should be in the ballpark..
