    Hi Guys.
    i have a problem with weelColider´s demonians someone can help me with him, my problem are the car has very recoil as run and see, the car has very little realism.
    PD: i see the tutorial the car, i import the car skeleton and i test with unity car but it`s all useless.

    i see the tutorial unity car, it´s good toturial but the car is not acceleration correctly and brake it´s too long time in brake for much zeros in the input.

    the import car like the tutorial wheels but i dont lose the hope.
    I have hope in community can help me. Thanks for all

    Hi, and welcome to Unity forums!

    Unfortunately, the WheelCollider component is so badly designed at its roots (PhysX) that making it work properly is extremely difficult. My own vehicle physics kits use the suspension part only. I've been unable to extract any logic out of the friction model and its settings.

    Some past forum threads on this:

    https://forum.unity.com/threads/is-there-a-way-to-gently-apply-brakes-to-a-wheel-collider.392855/

    You may find many more by searching for "site:forum.unity3d.com wheelcollider" on Google.

    The best recommendation I can give is to use any vehicle package from the Asset Store. There are several ones, choose the one that best fits your project. For example this is a free asset you may use as starter:
