Rough setup:
Kit springs, assoc 40f/37.5r (it's possible I accidentally swapped shocka front to rear, though)
Medium links, Front 1mm in and out, rear 2mm in and 4mm out
FF .5 out, FR center, RF .5 up, RR .5 up
1mm ackerman
Front arms forward
4mm bump steer
-1.5 camber
A pinch of toe out front (eyeballed)
Front spool, rear 2000
Mazdaspeed 6
5.5 with boost
Before, the rear mounts were .5 out. I think .5 up is better, but I'm just not sure. Front sweep seems good. I first tried just the FF change. Then I took it out again after other changes (just to see). Then I added it back in with arms forward to try and isolate it more, and I don't think it was as good.
But the tires take long enough to get heat, it's really hard to gauge the changes.
The big thing I haven't messed with yet is springs and shock angles.

I'd change the shell as first port of call if you've got understeer everywhere. An LTCR will liven it up.
