While a vehicle corners, the movement of suspension is focused on the intersection (instant center) of the lines extended from the upper and lower suspension arms. The intersection between the line from where the wheel contacts the road to the instant center (Point P) and the vehicle body centerline is the roll center (Point B). With the stock suspension, the appropriate roll center has already been set from the factory.
