My personal opinion is that the URD 3D model is not great. Some things I don't like and don't work on the car. The car needed more love when creating it. The ChemFlummi is much better because it is an ACC conversion. That's why I only created this Skin for the URD 296 and no others. Physics could be better for both cars. ChemFlummi has updates. There was sometimes better physics and sometimes worse physics. Currently I don't know. I stopped at V1.4. I think there is already V1.8
