    Hi all,

    I have been using the rf2 physics calculator to create a single seater chassis file, with measured hardpoints and links from the real car. However, after I add the changes the FFB has a strange feel to it where the steering torque drops off to nothing in some high speed corners past a certain steering angle.

    In addition there is an annoying high frequency vibration coming through the wheel when driving straight, which can be controlled by gripping the wheel harder. Does anyone have any advice on what I should look into to solve this?

    Log data.
    At what velocity does your HFV occur?
    What frequency is it oscillating at?
    In pitch, roll or yaw?
    What wheel are you using?

    Are you logging via Motec? Well worth doing anyway but you should be able to log the FFB demand against all kinds of things such as the dynamic camber, steering angle etc. etc. - often a lot easier to process than trying to pause the Dev environment and make sense of instantaneous figures…

    What is your scrubradius?
