LSD question

[domi]

Thanks for the feedback, but my question still persists:

Going on the idea that the 2-way diff has similar coast [engine breaking] and power [engine acceleration] torque deliveries on both wheels, then it'd be just as under/oversteer inducing in deceleration as it would be in acceleration. Understandably you can control whether one will exhibit itself in any way with suspension adjustments, but to be fair let's examine this as having identical suspensions on two identical RWD cars, one has a 1.5way, one a 2way. My way of thought is such, and please correct me where i am wrong, since it's obvious i am and therein lies my confusion:

Let's say both cars approach a 90° left turn in the same manner and coast in halfway through and at the apex throttle their way out. Car #1 with its 1.5way has sufficient control while braking and when applying torque it shows understeer due to both rear wheels going at about the same speed. Car #2 with the 2-way diff understeers on the way in due to rear wheels having about the same speed for a brief moment has neutral steer when applying the throttle and then continues having the same amount of understeer when torque is applied due to the same reason. What am i misunderstanding? Don't get me wrong, i can see how both rear wheels having near 1:1 speed ratio can cause oversteer when weight is taken off the rear end and then cause oversteer when weight is reapplied to it with the throttle being open, but it still doesn't add up, not to mention neither under- nor oversteer is considered good on the racetrack. Tirewear aside everything that causes fatigue to the driver's concentration by requiring more effort is a no-no. The way i've understood it is that neutral steering is best, then the racing cars manage to have neutral steering with their 2way diffs and that's what gets me confused: what could possibly be more neutral than open diff? Ok, it is a pain to have the inside rear tire spin on the exit of a corner - go for 1way or viscous link for all i care, but why 2way?
I hope you can follow my line of thought and sort this out, cause i'd seriously love to know what is wrong with it...

Cheers and best regards.
