and the speed limit menu :

function speedo()
    options.menu_subtitle = "LIMITEUR"
    ClearMenu()
    Menu.addButton("Sans", "vitesse", 0)
    Menu.addButton("30 Km/h", "vitesse", "30.0")
    Menu.addButton("50 Km/h"", "vitesse", "50.0")
    Menu.addButton("70 Km/h"", "vitesse", "70.0")
    Menu.addButton("90 Km/h"", "vitesse", "90.0")

add the function :

function vitesse(vit)
    speed = vit/3.6
    local ped = GetPlayerPed(-1)
    local vehicle = GetVehiclePedIsIn(ped, false)

    local vehicleModel = GetEntityModel(vehicle)
    local float Max = GetVehicleMaxSpeed(vehicleModel)

    if (vit == 0) then
    SetEntityMaxSpeed(vehicle, Max)
    Notify("Limiteur ~r~désactivé~w~, vitesse max : ~b~"..math.floor(Max*3.6).." ~w~Km/h.") -- Max*2.236936 for MPH
    else
    SetEntityMaxSpeed(vehicle, speed)
    Notify("Limiteur ~g~actif~w~, reglé à ~b~"..vit.." ~w~Km/h.")
    end
end
