I agree that the force on the steering wheel is influenced when changing caster camber etc. But still the fritction of the contact patch will be less when udersteering so less force on the wheel. And maybe with different caster and camber the percentage that the force on the wheel will drop might vary. And hey a can't say it enough I'm not a real world racer so I can't really judge what is right or wrong. But I also realise I m not driving a real car only a simulator that I personally think would be even more awsome if I could sense understeer through the steering wheel instead of seeing the car slide in a straight line and the front tires heating up...
