    And the new build will come with little adjustments to the tire grip and steering wheel according to the inputs and tests performed by Mr. Woller (@Michael Woller), formerly 2004 ADAC Formula BMW driver, together the full 2004 season liveries, helmets and visors.

    In the next week I'll finish painting the last team, then we must wait for @Leonardo Nogueira pending helmets. Unfortunately he is very busy and he needs time, but his helmets are awesome and the time we must wait for will worth!

    Without forgetting the mod was originally made by iDT and improvements to the physics were mainly due to the porting to rF2.

    Last skin of the 2004 Germany Season, now we must add few more helmets and visors before the public release.

    Hi, new FBM physics feels really enjoyable, and lots details, though the balance is more toward understeering. And we do find a strange behavior with tyre, even with very understeering setup, rear tyre wear is still a few times more than the front. the huge wear difference doesn't seem logical consider the car is understeering, the rear end wears way faster than the front, even when you are running a extrem understeer setup

    Hello Marco,

    First, thank you very much as well as everyone involved for updating this mod. It's absolutely one of my favorite car & mod.

    I'd like to report a potential physics issue with the tyre wear.

    Here is a lap data @ Loch Drummond with default setup, as you can see, the rear tyre has 4 times higher wear than front tyre (normal driving):
    upload_2021-12-3_14-51-11.png

    Then, I decided to take a look at TGM files, and noticed a huge AbrasionVolumePerUnitEnergy value difference between front (200-540-13X8_SLICK_2018.TGM.tgm) and rear (220-540-13X10_SLICK_2018.tgm).

    See pic below:
    upload_2021-12-3_14-55-48.png

    As you can see, the purple outlines are the values used ingame.
    The blue outline is the old value that was commented out, but is still presented in rear tyre TGM.

    And I'm suspect that the new AbrasionVolumePerUnitEnergy value from front tyre TGM was forgotten to put into rear tyre, which resulted the huge tyre wear difference.

    Also a few other reasons to support the above speculation:
    1. both front & rear WET compound TGM use exact same AbrasionVolumePerUnitEnergy values.
    2. most mods, including official mods & tyre samples, use same AbrasionVolumePerUnitEnergy values for both front & rear tyre of the same compound.
    3. after I copy the front tyre AbrasionVolumePerUnitEnergy value to the rear tyre TGM, motec data shows even & small tyre wear difference between front & rear. See pic below (default setup).

    Please take a look at the issue when you have time.

    And thank you again for the great works!

    ….and maybe take a look at the fuel consumption :rolleyes: — these cars use the double amount of a tatuus

    Thanks for the detailed info about tire wear! I must go to look at the changelog of the development, because sincerely I do not remember the reason of this difference; it is probable that I made a mistake.

    About fuel consumption, I didn't changed the value I found and written by IdT at the time they developed the mod for rF1 and I haven't search or asked for data... it is a very old engine, so the consumption could be true, but it is only a supposition... I'll search/ask for data

    BTW, I was just investigating on the car about the FFB strength that, here (G27) for this kind of car looks good, not very strong but not weak.
    Does somebody feel it weak?

    Do front and rear tires wear at the same rate even with identical tires?

    I don't think it. Front or rear traction, as well as driving style, understeer, oversteer change the wear, also if data inside the TGM use same values in the real time section. Do I misunderstand your question?

    Can somebody let me know his feeling about the FFB? It was tested before releasing the mod and shouldn't be weak, but different devices and DD can give different results...
    If possible, with the default setting and reporting the kind of device in use, can please let me know your feelings in easy way...
    device=xxx - FFB okay or too weak
    Thank you!

    device= Thrustmaster T500 F1 addon. Settings windows default. Vibrations in the PIT line with limiter placed and large straight to Max Speed. Also vibrations in strong braking. Reduce torque 2% but continues vibrating. The FFB feels good upload_2021-12-8_15-16-52.png

    first post has been updated with build 1.65 for fixing black rain on certain tracks, due to wrong rF2 code
