do a search in the workshop for stock cars. I currently run in a cup car series and I know of a xfinity series and a truck series is available also. Not aware of any dirt series although the is a dirt track available. Its the one that Tony Stewart runs I believe.

i have been working on a sprint car and a late model for dirt racing but have very limited knowledge of how to convert it from Assetto Corsa to RF2, i am trying to find someone to help me convert the cars and tracks over, if you know of any modders let me know because the cars and tracks already work in Assetto Corsa so it shouldnt be too hard to make them work in RF2
