More than a year ago Nadeox1 made a video of an F1 car with some rather stiff physics. Has he made any improvements since then?
It's long gone. The one in the video was one I made quickly with some hackery, taking a model from one of the free models sites, and heavily editing the GTR390 Jbeam. The formula I was making by myself instead is just dead. Those things require much more JBeam experience than I have.
Must be ultra hard if you are saying that. You are one of (if not) the best modders for BeamNG and RoR!
