Title really says it all. The parameters for the vehicle seem like they support a suspension simulatin (there is minimum and maximum displacement,) but no matter how I drive and turn, the sedan does not tilt to the side. It’s as if the center of gravity was in the same plane as the wheel contacts.
So, the short answer is: Set the “Suspension Force Offset” value in each Wheel Blueprint (front and rear wheels) to -20.
The long answer is: There seems to be some magic anti-roll going on. Setting the tire friction really high, driving 70 mph, and then making a hard turn doesn’t flip the car over. Even driving fast with the left side of the car onto a ramp and the right side on ground, seems to apply magic car-righting forces to rotate it to the normal-up orientation.
