Re: torsens and slip
no!
that is exactly what i am *not* saying.
i am saying that the torsen doesn't *care* about slip angles because, in the
vast majority of cases, they make *no* difference to the coefficient of
friction delivered by the tyre to the driveshaft. reference carrrol smith.
i am *not* talking about loss of grip here, i am talking about slip angles.
not sure that i can make it clearer than that.
