Why is the car roll center always designed to be lower than the car's center of gravity
In my humble opinion, despite the fact that the car suspension will be harder to install and that there will be interference between the wheel and the car body, having the car's suspension roll center above its cg is a lot more beneficial as:
1.) the roll of the car will counter the car's lateral weight transfer during cornering, which helps the car to corner better. 2.) the roll motion if the car also helps the car roll into the center of the cornering, which prevents rollover of the car.
Please give reasonable explanation about this, and please avoid giving reasons such as
1.) the perception of the driver will be better while cornering if the roll center is lower than the cg 2.) the suspension is harder to install to the car
Because i find that these reasons are not good enough to out weight the benefits gained written above.
