Advanced Vehicle Template : car not slowing down in corners

Hi there,
I’m playing around with the advanced vehicle template and am trying to assign audio to the car.
At the minute, the vehicle does not slow down at all when it is taking a corner, which is unlike what a car would do in any racing game or in real life
Just wondering, does anyone have any tips or tricks to make the car slow down when it is taking a corner?

Thank you in advance!
