Try something like this:
Front shocks inside on tower out side on wishbone
30 wt orange with blue springs.
outer camber link on tower & hub with 2 washers.
30 grans of lead in front (20 infront of servo & 10 upfront.)
Rear shocks on the inner hole on tower & inner 3rd hole on the wishbone (extra hole drilled 9mm further in- this makes a huge diffrence)
30 wt oil orange pistons & pink springs.
camber link middle & middle.
2deg anti squat & 3deg tow-in
Running swb chassis with short wheel base at the hubs aswell.
I found this setup very good with Lipos
The short chassis and the extra inboard pick up for the rear shocks makes a huge diffrence!
looking at the setup you have now id try swb & a softer rear end first & go from there.
