Wing breaking off on sim damage

I was doing a forza gt race on sim damage and I swiped a tire wall and my rear wing came completely off. I didn’t really notice a difference in the cars performance except maybe a little better straight line speed. I checked the damage menu mid race and it said the rear of the car had 0% damage.

So does the wing falling off on sim damage actually affect anything? I would assume it does since it’s called simulation damage, but I didn’t notice much difference after it fell off

Maybe the wing isn’t included in the rear damage. Like it isn’t included in the rear of the car in the paint editor? It’s it’s own entity with separate locations for vinyls.
Maybe it’s the same with damage. Now if you can’t see that damage because there’s no entry for wing, that would be another matter. Either way it probably won’t get fixed, as it’s got a long list of bugs in front of it.

I had a wing come off rubbing a wall, didn’t even dirty the lap… It’s all cosmetic doesn’t affect handling

Yes. The wing flying off has always happened. I don’t think it has ever affected the cars performance though.
