not a tuning tool. You would use shock settings, tire pressures, ft suspension tuning, etc, to get max traction.
As for an angle, I use 3-4* down on the pinion.
The suspension components, & bushings must be of a good quality, in order to minimize deflection.
I also use the HR antiroll bar, no air bags, [new] stock springs.
On the ft I use the Moroso BBC springs, and adj shocks, no sway bar, stock bushings.
I used the single adj HALS on all 4 corners. They worked well, but I would go to dbl adj shocks, if I was to replace them, or make an initial purchase. [NOT cheap, but adj shocks "git'r done"]
NO SNUBBER!!
