I agree Jmac with Syracuse, although there is the DW_ntmc mile that has decent ai, I use that for my super dirt week in my series. I dont know if somebody could take that as a base and go from there. I wouldn't mind posting the series I made, I can't take any credit for skins or tracks, basically gathered up all the latest modified skins I could find and put them in a super dirt series, and also made an RoC Series with some skins from the 2004 southeast series and some of the newer skins that have been made past few years of the local/regional guys. And then for my sportsman series I am using the sportsman chassis which is fun to drive, and found a few sportsman driver skins from a few years ago and took the not so big name guys with big block skins and converted them to the sportsman chassis and put that series together.
I wouldn't mind seeing if we could a 358 dirt series made, I know there is one around somewhere from the past but I can't find it, it was the Turning Stone Casino Series. I had it on my old cpu, but cant find the cd I saved it too and can't find it on the web anymore.
