We will be back soon! In Bearbeitung und bald zurück!
PG-CarRig: There is a plugin called Easy CarRig. It is almost the same :D Very very close, with some improvments. You can download it for free at c4dtools.net
All the other presets are deleted for now but you can still watch the videos on my vimeo site and rebuild them yourself.
See ya and thanks to everyone who gave me feedback :D
