maybe your UFR is simply old...

That is what i wanted to know, if this can happen in real life i'm ok with it... but any other LFS car isn't so easy to "hit the roof" with it... like the XF GTR would have the cantre of gravity near roof, or even above it

I'm not really sure if this is a bug, but the XFR flips all the time... What do u think about this ?
