How do I increase "tire grip" and reduce sliding?

[brickyt]

Amazing job with this vehicle controller! Best godot vehicle demo I've seen out there!

I am going for a simcade feel for my prototype and wanting to reduce the amount of sliding/slipping when the car is at high speeds and turning fully left or right.

Any help or tips would be most appreciated! Cheers!

The traction_limit, longitudinal_traction_curve_scale.y and lateral_traction_curve_scale.y properties of the tires are probably what you're looking for. Try setting them to a higher value, maybe something like 1.5 as a start. longitudinal_traction_curve_scale.y affects acceleration and braking, whereas lateral_traction_curve_scale.y affects steering. They don't have to be equal, but traction_limit should normally be set to the larger of the two curve scale values.

You'd probably also want to lower the vehicle's center of mass, otherwise it will roll a lot due to the high grip forces.
