Why is my Chaos Vehicle sliding that much? Despite high friction values

As the title says.

I have setup a Chaos Vehicle (C++) with a custom mesh. I have no issues with physics (collision seems ok, wheels are colliding, etc.).

These are the Wheel BPs (UE5):

To test the driving behaviour, I use a plain landscape.

No matter how I change the friction values in the chaos wheel blueprint, my vehicle is very slippery in UE5.

In UE4 I use the same friction values for the wheels and in I can make sharp turns even with speeds > 100 km/h without sliding. I didn’t even had to add a physical material to increase friction.

These are the Wheel BPs (UE4)

What did I miss? I know that UE5 is still early access, but then maybe I should submit a bug report on this?
