Unfortunately I currently store orientation in map file only as an angle and not full matrix so it would be a lot of work to allow full rotation in all axis.
oh, so maybe you have put this thing on your todo list ?
another question ; do how to change positions of the wheels ? i only see one wheel on the file with the car :(
It is currently hardcoded in the engine but it is the main goal for next release to have vehicle fully configurable in a config file.
