AngusF1 Pay attention to the yaw inertia. I did it on a real car many many years ago (built a new suspension for the whole car, maintaining constant all the possible variables of the narrow version suspension). I was the driver too. The project was disappointing. The car got slower. What I felt was the car was lazy to enter the corners.. I think I forgot the yaw inertia. I had not many time to think about it.
