Vehicle wheel friction values are applied too high relative to the vehicle centre of mass.
They are applied at the wheels original rest position rather than the base of the current wheel location.
Can also show forces that are applied by using the CVar p.Vehicle.ShowAllForces 1 along with p.Chaos.DebugDraw.Enabled 1 but you have to know what lines you are looking for.
Can see blue lines coming from wheel arches.
Run the vehicle template project UE5-Main\Templates\TP_VehicleAdvBP
Adjust the vehicle suspension setup so the drop length is 100 units drop instead of (currently 10 units).
This "Suspension Max Drop" parameter can be found in the wheel BP assets SportsCar_WheelsFront and SportsCar_WheelsRear
found in the content directory Content\VehicleTemplate\Blueprints\SportsCar\
After these adjustments, play the level. The vehicle will drive around without tipping over even though it's driving on stilts.
Expect the vehicle to topple over or at lean lean due to high centre of mass, if the forces were applied at the correct location.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-160172 in the post.
