Interesting FFB behaviour when at steering lock or very low speed

The wheel "jumps" into steering lock either way and won't straighten out by itself. I noticed that it's not like that in iRacing for example, where you can turn the wheel fully and then as you accelerate it will straighten out. Is this by design or is it something that should be reported as a bug?

SC2 Sport at ~45% with all default settings. FFB is not inverted - it's fine when driving fast.

I’m no good with recognising cars from onboards - is that one of the hypers with “interesting” steering geometry per the known issues list?

If so, despite being in the known issues, it’s not an issue. The low speed centring force in most cars is from the way the various suspension and steering components align, and in some cars it’s different enough that you actually lose it and it can even invert.

At speed other factors come into play and you get a more normal centring force.

"FFB is not inverted" it sure is acting like it is inverted... looks like a bug for sure. I don't think this is the case here but some Moza profiles invert FFB for different games. EG: my AC EVO profile is flipped from LMU... but that is not the same as at low speed only.

I'm experiencing this as well, it feels like the FFB gets inverted at very slow speeds. I've noticed this on the BMW, Cadillac and the Ferrari so far. In iRacing these 3 cars does not behave like this.

I think this is a bug? Though I'm no expert on how these cars are meant to behave but it's kinda strange how these prototypes in particular have these handling characteristics at low speed.

It’s how they are. Ferrari explicitly confirmed this when the devs queried it. (This was mentioned on discord, which is why I’m happy to repeat it; I don’t know about the others, but that doesn’t mean they’re wrong)
 
I'm looking for it on the LMU discord, can you share the post (or posts) about it? Curious to hear what the devs/ferrari have to say about it
 
Thanks I found it. As well as these notes from the same discord post: 1740373439843.png

Are these notes from the devs? Because I have yet to have find the update which has this written in it.
 
Just realised the BMW hypercar isn't included in the list of cars with interesting suspension geometry, as OP demonstrated it also has the behaviour where the steering pulls towards the direction of steering at lows speeds.

I couldn't find it in a "Known Issues" page in my limited searching, so does this mean this behaviour will be updated?

That known issues list last got updated at the same time the BMW was introduced. The geometry statements were already there before that.

I’d consider it more likely that the geometry of all the cars is correct, so if the BMW does this it’s intended.
