In Vehicle Movement component of chaos vehicle, there is a parameter “Legacy wheel friction position”.
Anyone happens to know what it’s supposed to do?
It affects car handling, but can’t say how exactly, as it’s difficult to reverse engineer because it works in conjunction with many other parameters.
It would be really nice to have some covering docs. 
I’ve found this in the release notes about this setting: Unreal Engine 5.1 Release Notes | Unreal Engine 5.1 Documentation
Specifically this:
- In the Chaos Vehicle Plugin it was noted that the wheel forces were being applied to high up and not at the road surface.
- Rectifying this means vehicle handling will change dramatically, likely requiring a lowering of the center of mass by approximately the wheel radius to get the same result.
- To alleviate this issue a new property (bLegacyWheelFrictionPosition) has been added to retain the old behavior. This will automatically be enabled on any existing vehicles but will default to false on any new vehicles that are created.
- To ensure all your vehicles are consistent on existing projects, ensure bLegacyWheelFrictionPosition property is enabled on the ChaosWheeledVehicleMovementComponent.
Ah, ok - point of force application - it finally makes some sense. I mean I ended up with some empirically found parameters, but understanding some logic behind really helps. I appreciate!
