A posi rear that loses traction in either snow or rain is going to make you do donuts......not good
Ever see a car with posi traction do a burnout on dry pavement....car goes sideways, fishtails and all sorts of crazy stuff.
Imagine that in the snow or rain....when you don't want it to.
An open rear is going to spin only one wheel and the car will remain straight which is good for poor weather but bad for the drag strip.
