Wheelcollider turns too sharply

Hi

I have made a car using the car example from the vehicles package in the Standard assets. However, even though I have experimented with multiple settings from numerous suggestions, every time I try to turn, it ends up turning a very dramatic, unrealistic, sharp 90º turn, feeling very lightweight and like I have little control over the car at all. This is unlike in Unity 4 where it felt like I had a lot of control over the car and it turned far slower, and at a more realistic 45º angle. Anyway, my question is, how can I change the settings so that I can make my car feel less lightweight and so that it will turn slower?

Thank you

Dok
