Vehicle Physic Asset causes high jump impact

So I have a vehicle (without visible wheels) which can drive around fine, but when I drive against a wall for example or other obstacles, the vehicle jumps very high into the air, so something is wrong with its physics.

I use the normal vehicle template as a base for my game.

My current physic asset looks like this.

Can you please help me?

Hi Eduard,

Try increasing the mass of your vehicle! I set mine to 3500. It behaves less erratically and is more steady.

I increased the box area dramaticly around the car, and now the wheels dont hit any obstacle first.

Thanks for your help, the mass is now something around 3800 as well without an override.

Still, sometimes the issue is present.
