    Hi everybody, thanks for all the advices and supports you gave me snce i start to mod on rFactor2.

    i'm trying to go deeper in the hdv, pm and all the ini files to really understand all the physics parameters and have the possibility to reate my own mod starting from scratch.

    my problem at the moment is the following:

    i have all the suspension point of a formula car, with pushrod suspension, already put in the rFactor2 reference coordinates system as following(first 3 are body, second three are ptboard):

    forward upper( 0.1903 0.3686 -1.455)( 0.6325 0.3769 -1.334)
    rearward upper( 0.1913 0.3515 -1.075)( 0.6325 0.3769 -1.334)
    forward lower (0.05 0.1573 -1.460)( 0.692 0.155 -1.352)
    rearward lower( 0.052 0.1612 -1.010)( 0.692 0.155 -1.352)
    steering arm (0.189 0.3686 -1.513)( 0.6665 0.3788 -1.429)
    Pushrod (0.0774 0.5841 -1.173 )(0.6243 0.1802 -1.332)

    i have no problem to create the pm file and later the chassis ini, but i'm in trouble to define pushrod inboard and outboard in hdv?

    how can i define it?

    can someone make me an example with my data?

    thanks a lot

    Hi Jokeri,
    thanks for the advice, but i'm trying to build my own spreadsheet, and i'd like to try to better understand all the line of the hdv and others files.

    thanks again

    To learn more about the hdv and other files, look into the devmodes skip barber files, that have a lot of comments for the entries.
    To build an own spreadsheet makes no sense at all in my opinion, because you don't know the complex calculations that are made to, for example, create the chassis.ini.
    To get proper results, i would strongly recommend to use the official spreadsheet.

    Fully agree with Bernd. Why create your own spreadsheet when there is one there with all the calculations. Before the spreadsheet I would load into ptool with a copy of my chassis and add constraints for the pushrods, steering table etc. Sooo much easier with the spreadsheet.

    Hi Bernd, Hi TheGame316,
    thanks for your advices, but i try to put some values in the spreadsheet, of a Reanult WS 3.5 and i don't get the same results of the mod i have, so i'd like to understand all the formulas behind that to understand the mod i find, and completly understand all the mods i have to do.

    i understand is complicated, but have to do this for a racing team, that has its own static simulator, and i need to be sure to create a perfect mod to replicate best i can the car's model for them to help their drivers to train with the real car. this team race in more than one category and they decide to switch from rF1 to rF2 due to a better quality of the model, so i have to learn this system now.

    after that for me will be very useful have some help about the formulas used to make that counts, and all the way has the program to use this data.

    thanks again

    If you do it for a real raceteam, i even more would recommend to use the official spreadsheet.
    I know one of the persons that have made the GP3 mod for rfactor 2.
    They have used as much real data as they could get and filled the spreadsheet with it.
    And they also have been supported by some real GP3 teams, that did testdrive the mod, to give some feedback from drivers of the real car, that the modders could finetune the data, that the car got the best similar behaviour to the real car.
    With that method you should get the best result for every mod.
