    Hello everyone, I am looking for the following information for project purposes.
    - Weight distribution of an L880K first gen 0.7 car
    - Suspension motion ratio (front and rear), - swaybar motion ration (front and rear)
    - Frontal area
    - coefficient of drag
    - coefficient of lift
    If anyone could provide this information I would greatly appreciate it.
    Thank you in advance

    Im getting an l880k copen model made for a racing simulator Assetto Corsa and to make sure the physics are correct I need to have these values, Can't seem to find them on the Internet.

    @AFR0N1 is your best bet, but I’ve never seen such detailed engineering information in the public domain for any car before.

    Weight distribution and coefficient of drag are often in the marketing material but is unlikely to be specific.

    Good luck anyway.

    Although I know a lot about the Copen, the info you are asking for is the same info I've been unable to find for ages now.
    Maybe putting a model of the Copen into some sort of aerodynamics simulator would be able to calculate some of this for you.
    I'll still be on the hunt for info.

    Not massively helpful but I found this recently:

    I translated some of it and it basically just says lift at the rear of the new Copen was reduced by roughly 60%
    and that it is 6% better for something.

    I'll do my best out of that Thanks a lot, I'll come back here with the results when it's done.

    I have found this on a german site, but I cannot confirm that this is genuine information:

    Copen L880
    0,382 drag coefficient
    1,62 frontal area (in m² - I guess)

    I just installed this mod on Assetto Corsa. I assume this is the one you were working on?
    Either way, it feels great to drive and accurate to the real thing (apart from it having a lot more power than factory)

    More on topic for this thread, I have found out the damping force (in NM) of the original dampers
    スポーツショックアブソーバーType-S

    And here's the spring rate

    And finally anti roll bar

    It was nice of Dsport to include a before and after of their suspension changes

    Did you have a link to the copen mod in assetto corsa at all?
