Oh, this? Would you mind showing us audio proof that the AMG GT S actually has any of those noises you mentioned? Apart from the burbling, which is missing (although in bumper cam it's much harder to ear that kind of noise), nothing else really matters and/or is barely noticeable in the real car.
Suspension noise? Traction control rattling? Gear wobble? What do you thing this is? A race car?
Well, yes, that's nitpicking when you want noises that are barely noticeable at all in a modern road car, to be present in the game. You won't hear suspension noise when there is engine noise present, because one is ten times louder than the other. People these days get delusional due to those games that exaggerate every single sound the car makes...
