A little toe in on the front is great for driving on the highway. It does make the car feel more stable. But is doesn't really increase stability, rather it reduces the effects of steering inputs and creates understeer. Those are definitely safer for the average driver on the street.
But for autox you definitely don't want dampend steering inputs...you want immediate response to make corrections. And understeer is better dialed in using another method, such as swaybars. The consequence on the street is that the car is more twitchy and will track grooves in the road. But for someone who autox'es frequently, the added work while on the road is not a big deal...it is just part of driving.
