sorry for late reply, meeting leh still working today.
one question, from my point of view, as you bring out the inertia
you are correct to point out that higher momentum need higher
initial to change the direction.
so can I put it this way, if at the same speed for both heavier end
lighter car to change direction, the heavier need better grip on
the tire in order to provide higher inertia for the car to change
direction?? (more power needed to provide higher inertia).
base on same road condition, same tire used the heavier car will
have oversteer first because with the same level of grip (same max
inertia), the lighter car can achieve a direction change at a
higher speed due to the fact that it need lesser inertia to change
direction.
When I reading on oversteer, it is the rear wheel which looses the
grip and still moving along the initial direction without following
the direction change of the front wheel. correct me if I got it
wrong.
lets assume both same car, same design, same tire, same road
contdition only that one car fetch more ppl than the other to
create the weight different.
