The front needs more camber. The front tire is probably rolling over and riding on the sidewall. Once you give the front more negative camber though, you will experience way more grip and way more oversteer
I believe the fr-s is more oversteery than the brz and that is at lower speeds. I've never seen a car that becomes more understeery at higher speeds. It always becomes looser as the speeds increase. Can't explain why though.. as far as lawsuits, the vsc does a pretty good job of keeping the car on the road and going in the intended direction.
