Moparx, that is a lot of negative camber for a street car. If the tires are narrow, it might be workable, but narrow tires aren't my wheelhouse. On a road course, it would be almost overkill, but would have great "turn-in" until the tires likely wore out. I would dial that camber number back first and see what improvement it makes. No way your posted caster numbers are overkill IMO.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
