I just did another to test it out. I installed this mod.

It only comes as an ADDON so I extracted the files from the dlc and applied to handling,vehicle meta files, along with the ytd,yft files to replace felon2. The car spawns perfect and dials work also.
Id like to mention that I'm also using this mod that may have an affect on this.
