    Im having a wierd problem with the wheels of a car :/
    Ive done the model in Cheetah3D and its being imported correctly in Unity
    But when im using the script from the carplayground demo it flips the front tires so there lying on the side...

    The wheels is 2 cylinders rotated +-90 degrees on the z-axis and it seems that its the problem...
    Ive found that its this line that resets the Z-axis to 0, how can do to just adjust the Y-axis?

    frontRightWheel.localRotation = Quaternion.AxisAngle (Vector3.up, m_Steer * Mathf.Deg2Rad);

    The easiest way to fix this is to model your car so that the wheels and the car is rotated exactly like in the car demo.

    The car and wheel z-axis must go forward.

    The wheel x-axis and car x-axis must go to the right, when you view the car from behind.

    I am sure cheetah has some way to change the rotation of the transforms without actually moving the geometry visibly.
