I think the feel of increased grip from a wider car comes from the lower polar yaw inertia. not from weight transfer to the outside wheel(s)

with the long narrow cars, the weight distribution is much longer in the car, once it starts to slide, it keeps sliding.

with the cars that have a wider and therefore short length of weight in the car, it is easier for the tires to slow its yaw down and get the tires back inside their traction limit and this makes it feel like it 'snaps' back into grip again.
