    Hi,

    I have pick whipped the Z rotation of a wheel to the X position. I want the wheel to move a lot faster. How do I increase the speed the wheel turns whilst keeping with the speed of the car?

    comp("Side Cards").layer("Silver Car").transform.position[0]

    You just need to multiply it by some factor. For a wheel rotation, it’s probably going to be something like this:

    factor = 360/(width*Math.PI);
    comp(“Side Cards”).layer(“Silver Car”).transform.position[0]*factor;
