    Yes

    FrontWheelTrackRange=(1.3525,0,1) // if non-zero, forces the front wheels to be specified track width
    FrontWheelTrackSetting=0

    (with an upgrade, you could modify this even with DLC, by using += and putting the figures you want to add)

    What happens, if you edit the HDV and also adapt the X Position of FL_WHEEL and FR_WHEEL in the flex Chassis.ini?

    Changing that value in the HDV should only change the front track. It just moves the chassis defined points in or out accordingly.

    fixed it by setting the tracking to zero in hdv file and moved the wheels using 3DSimED
    but thanks for your help.

    So you only made graphical change by relocating origin point of wheels ?

    …somewhat related…

    Do the HDV track and wheelbase files alter the physics - or just graphical offset relative to the body?

    I’ve inherited a mod to polish for a League Edition that has two visually different vehicles that have fundamentally identical config files (same tyres, engine, chassis etc.) - except that one has a slightly longer wheelbase and wider track in the hdv…

    If it’s just a graphical setting, I can strike it off the BOP list…

    I'm 99.9% sure it's physical. Back in rF1 some mods used wheelbase and track entries to make different cars different (Formula series, that sort of thing). I would say despite now using chassis files these entries still override the positions.

    If you load up the skip barber in devmode, drive a lap, then adjust the front or rear track using the above entries (by, say, half a metre) I think you'll notice a handling difference.

    As far as I know the only entries that don't affect physics are labelled as such in the comments.
