Simple answer that you wont like: there is nothing like a "suggestion" for values. It is up to you to play around with values until you find something that you think is a good behaviour for your car.

What you should start with is to get the damping and spring values to a good point that fits the size and mass that you gave your car. (Noone can guess values for you without given information) I'd suggest you start your scene with the car in it and modify it live while playing. Don't forget to write down te values when you are happy with them. They will be set back when you stop the scene.

The probably most intresting values after that are the force app points and the side friction and forward friction. The higher your force app point, the less likely your car is to flip when you enter a curve with high velocity. For the friction parts you should only modify the "stiffness" value which is basically an amplifier for all the other values in the side/forward friction parts. The higher the stiffness, the more grip you will have on the ground. Make sure that your sideways stiffness is always higher than the forward one.

Hope this helps. For future questions it might help if you provide more information about your problem than just 1 written line.
