Hi, I love this app and have been using it now for over a month. Some of the content is a little dated so I was wondering if it was possible to add new cars and tracks myself?

Also going further it would be really awesome if I could even rewrite the cars and tracks for a different game? Say if I wanted to make it relevant to rfactor 2?

Thank you
