This is my overlay once experimenting with the editor from Happy Medium DynHUD for my widescreen monitor 2560x1080 but can be used for standerd 1920x1080 if preferred.
Practice & Qualifying
just extract to C:\Program Files (x86)\Steam\steamapps\common\Automobilista\Plugins\DynHUD\config\overlays and in game select WideScreen Max HUD from Options->Display->DynHUD Overlay
Try it out and see if it works for you
