    Your toe-in/out explanation aren't reversed for the front?

    In every guide I could read since a decade for many sim racing game, I always read that : Toe-out in front give more stability in corner entry but also add more understeer when cornering

    This is what you wrote for toe-in.

    Perhaps the definition of understeer is used in that explanation? i.e. the tyre slip angle is higher in the toe in case vs toe out at the same conditions in the turn. More slip angle means more understeer at the front tyres. On the rears the signs are reversed so they have more oversteer at higher angles of slip.

    In that case, explain the toe-out to the front for every preset given by the game (safe and aggressive).

    If the explanation of the OP wasn't reversed for the front toe-in/out, that would make sense.

    I'd better let someone more versed in the setup game do that :D

    [QUOTE = "djshivas, post: 1170962, member: 10337"] Is your explanation of convergence / opening not reversed for the front?

    In every guide I've read for a decade for many sim racing games, I've always read that: front divergence gives more stability when cornering but also adds more understeer when cornering

    This is what you wrote for convergence.

    @djshivas
    Can you tell us which setup guides you are referring to?
    Here is what is written on the BRSCC (British Racing & Sports Car Club) website about the Toe out on the front wheels:
    Toe out on the front wheels is a common setting as it will help to improve turn-in response and help to reduce understeer.

    With the introduction of the 1.6 version of Assetto Corsa Competizione it is possible that the optimal tire pressure window has narrowed compared to the 27-28psi range reported in the guide
    imho

    correction: it is sure, the optimal pressure window is now 27.3 up to 27.8
    Thanks for bringing to awareness, tho. :)

    In one of his latest streams (Spa, I think), Aris mentioned 27.4 as lower boundary.

    Would this optimal pressure windows apply to both GT3 and GT4 cars equally?

    No, GT4 have lower optimal pressures.
    For that I'm not quite sure, I would have to re-check but from memory I would say it's from 26.7 up to 27.5 ...

    And wet tires have way higher optimal pressures (equal for GT3 and GT4), I always try to get them to around 30.0psi but I don't know the window boundaries, too rarely I race in the rain.

    If someone has the right numbers, feel free to post it. :)

    Hi AndyK70 - Thanks so much for the reply. I'm still running between 27.5 to 28.0 on my GT4 McLaren. I ran a 20 minute race at Spa yesterday against the AI in the Championship series and it seemed to be fine. I'll have try going down to 26.7 to 27.5 to see how my lap times are affected. Thanks again for the feedback, it's appreciated. :cool:
