To be honest, I hardly can´t tell any difference in grip levels running different wing settings. I do notice increas of drag with higher values (although not as much as yuu might have expected for example going from min to max), but I noitice very little increase in corner speed, and balance when chaning the wing settings. Is this some kind of bug? To me it seems like they made the wing settings have too little influence on downforce. One thing that supports this theory is that on most (all?) circuits, rearwing = 1 gives the fastest laptimes. I think this is a shame, because it takes away the challenge of finding the optimum balance between speed and downforce on each track. As it is now, a 1 / 1 setting works fine for every track.
