    I know I am late to the party.

    I was just able now to try the Cobra, what a car!

    Cockpit is stunning, took it directly to the track, adjusted brake balance, and after a few cautious laps I was pushing the beast.

    I don't want to analize the reasons, but I must say I have never driven a car with such a feed back, you know at every moment how far you are from the limit, the car is pure joy to drive.

    Congratulations ISI.

    Sorry if already covered but is Toe in/out backward? I.e. I am getting better turn in by increasing POSITIVE toe in front. I thought increased NEGATIVE toe in front was supposed to help turn in. No?

    Yes but will make the car more prone to wander left and right on straights.

    "Increasing negative toe in increases straight line stability, so it won't help turn in."

    Cheers.

    I was wrong, Spinelli is right: I called negative what is positive.

    I should have written "Increasing toe in increases straight line stability, so it won't help turn in."

    Toe is a measurement of how much the front and/or rear wheels are turned in or out from a straight-ahead position. When the wheels are turned in, toe is positive (+). When the wheels are turned out, toe is negative (-).

    + toe (positive toe) = / \ = more stable less turn-in

    - toe (negative toe) = \ / = less stable more turn-in

    I agree with Spinelli this time :)

    That was also the way that I learned it

    Thanks guys. So now why am I getting better turn in with more positive toe?

    Then the settings are probably backwards in-terms of how they're written.

    Or maybe the setting is called "negative toe" rather than just "toe". If that's the case then a positive number would equal negative toe (toe-out) and a negative number would equal positive toe (toe-in). That's a pretty messed-up way of doing things but it would still technically be correct.

    You're tightening the radius of the outside tire, which is the loaded one, and if you're also loading the outside tire quickly enough it's possible to get better turn in.

    Could be wrong here, but I've always been led to believe that toe-in improves steering response, basically for the reasons explained by Isosceles Kramer. Toe-out can help improve grip to the steered wheels, while they are turned, at the expense of stability and steering response. Could it be that you are mistaking improved steering response for better road holding from the front wheels in a turn? I find it helps to visualise what the wheels are doing when they are set to toe in/out and what will happen when you turn the steering.

    That would be my guess as well.

    One explanation about toe-in and toe-out:

    Another one (starting from 3:02):

    https://www.youtube.com/watch?v=d0voTx7AuZQ

    IMO when speaking about toe it should be mentioned whether it's in or out. So if we're looking a car from above (having zero toe on rear) then:

    Positive toe-in:
    //-----\\
    ######
    ######
    ######
    ||-----||

    Negative toe-out:
    //-----\\
    ######
    ######
    ######
    ||-----||

    Positive toe-out:
    \\-----//
    ######
    ######
    ######
    ||-----||

    Negative toe-in:
    \\-----//
    ######
    ######
    ######
    ||-----||

    Agreed? :)

    +1

    Otherwise it's like saying it's 10 degrees C outside without mentioning if it is +10 or -10.

    Sorry can't remember whether I posted these specific details before but since I had to dig into VEH and RCD files again I figured I might as well copy paste what I am seeing here for ISI convenience so can be fixed in future updates...

    Alessio Romito is assigned to four cars (427SC_black.veh, 427SC_blue.veh, 427SC_red.veh and 427SC_silv.veh) which he cannot drive at the same time and therefore rF2 will assign random drivers to three of the four vehicles.

    Here is what I have added to my offline racing kit at professionalsimracing.com...

    Alessio Romito is assigned to four of the AC Cobras (427SC_black.veh, 427SC_blue.veh, 427SC_red.veh and 427SC_silv.veh) which he cannot drive at the same time and therefore rF2 will assign random drivers to three of the four vehicles. Recommend assigning self to one of these cars, then selecting only one of the remaining cars at the track along with the remaining cars assigned to other drivers.
