As two famous radio show hosts would preface some of their answers by claiming the answer was arrived at without the encumbrance of the thought process, I too will apply that statement to my answer.
The short answer is no. The aerodynamics of an open wheel vehicle provides additional down force, trying to overcome the car’s forward inertia that is trying to keep the car going straight. The heavier a kart is, the more forward inertia it has as it tries to turn.
And don’t drive like my brother.
