I recently upgraded the Wheel Controller and discovered that a later release has some different behaviour compared to an old version I had when I purchased. But this is probably specific to my case. Basically I am making a miniature vehicle (about 1 m in real world units and Rigidbody mass of 20) and when I purchased the package I managed to get what I need. I am not sure what version that was, but the docs in the old files and also in 2.1 still says 1.5. Anyhow using the later version the vehicle is more bouncy and seems to be a bit less stable, and I can not get old behaviour back no matter how I adjust the spring and damper values. I was wodering if I missed some settings on upgrade or was there some fundamental changes done to the asset, that is less suited for small scale now.
