diRtFactor has essentially evolved into the DWD Late Models over time, many of the former dF members have moved on but there's a good core of the people behind it still there. If you're seeking an RFactor 2 version I'm fairly confident that Don, Rod and the guys will be looking into it after RFactor 2 comes out. Do not expect it to be out as soon as RF2 is out (might be months later, new updates to the gaming engine... gotta sift through and figure things out so be patient with them) so... for now, I'd just enjoy DWD Late Models v3 (http://www.dirtworksdesigns.com) on RFactor or continue racing diRtFactor.
