Well apparently it's built into the MX5 in iRacing, they call it ABS but all it does is shake the wheel when you lock up, supposed to teach rookies not to lock up.
However it does not seem to scale with FFB settings, it seems to be full power all the time. This cannot be good for the wheel.

Ok I found something out, in iRacing it only does it when driving the MX5 Roadster or Cup. It still happens in SRW for the GT86, RS500 and EVO. I stopped trying different cars then. SRW is a bit of a mess with the FFB anyway so I will forget that for the time being. But it seems in iRacing it is som...

Not the best vid and does not show how strong it is, but hopefully you get the idea.

Yeah I'm starting to think there is something wrong with it. Seems to make no difference what I do, and even with FFB turned right down it's still doing it. Will keep at it as Fanatec is closed for the weekend anyway I would assume. I'll try and catch it on video and post it as it might be useful to...

Its not quite as strong but it's not far off.
Just removed fanaleds, reinstalled drivers and FW (144/037) and re calibrated.
Still the same, seems to be some sort of effect kind of like axle tramp if you know what that is?

Thanks for trying to help btw.

It feels like the FFB test in the Fanatec software if you try to hold the wheel still.

Currently 92, but have tried various settings from 70-100. I have continued testing everything I can think of, I can feel the rumble motors in the wheel too if I turn it on in Fanaleds, it's just this judder, it's a violent and very fast but small oscillation via the FFB. But only when I lock the br...

This could be nothing to do with Fanaleds. I own the Clubsport Wheel (BMW rim) and the Clubsport V2 Pedals. (both on USB) Fw V037 Driver V144 My problem is that my pedal does rumble but it is delayed quite a lot. Along with the brake pedal rumble I get a severe juddering of the wheel, not rumble. Ho...
