    question for all of you:

    being this Yaw Center on car center line, shouldn't it only tell how much of the overall Yaw moment is coming from the front and rear axle? considering also Yaw Moments'...

    hillclimb tires? :)

    Anyway, regarding the front weight distribution, i guess one thing which still deserve to be mention is the differential.

    In my experience, it could change dramatically how...

    @jpusb,

    yes, i correct the corner radius for each output point of the diagram. Actually, since it is a constant velocity simulation, calculating the Fy gives automatically an Ay, so the radius is...

    Jpusb,

    here a picture showing the slip curve of a front tire i am using, with vetical loads varying between 2000 and 6000N.

    What is the point exactly in simulating the longitudinal forces if...

    From direct experience, reverse engineering the tire is a nice technique if you don't have any data at all, but it is at the same time very dangerous, above all if your driver is, for any reason, not...

    didnīt have time to look at it properly yet.

    Just one question anyway: does it allow to model Push/Pull Rod geometries by default, or they should be defined somehow by the user?
