Yeah, there is probably something screwy going on with the calcs, since you seem to be using the same suspension settings front and back as well. Let me tag @Killrob
Definitively some issues with the calcs. That’s with McPherson and Torsion beam suspension.
It also seems like sway bars do not affect over/understeer very much.
This is with 175mm tires on all corners and a 60/40 weight distribution on a compact car.
