I was wondering why I can only download LRP and the C6R? I thought PBIR and the SKippy car were also available.
You can download everything listed on rfactor.net, but the things you found are the only things released seperate. The other things are in packages (thus both car(s) and track(s) in one file). You can find them at the top of the download page, just under the build download EDIT :: in the future everything will be available for download individually, and then you will probably find the download icon behind the picture activated
