Daytona Sports Car Course with the GTE cars is on the server. It really doesn't get any easier then that. Unless you want to do open wheel cars. None of the tintops in AMS2 are really made to be used on ovals since they only have like 2 of them in Brazil and they both have infield road courses that get used way more then the oval alone.
It has to be understood that Rezia is a Brazilian based company mostly making Brazilian based tracks, cars and series. The first thing they did was a Brazilian Stock Car mod for rFactor 1 and they turned it into a stand alone game called Copa Petrobras de Marcas which is free on Steam. They then went on to make Stock Car Extreme, which turned into Automobilista 1 and then Automoblista 2, I know we North Americans when we hear the term "stock car" we immediately think NASCAR, but these cars are so far from the NASCAR type stock car there is no comparison. Sure you can spend hours adjusting on the set ups to make the only turn left and for some people that's fun. But, the original attempt here was to make this a fun series with little to no effort, ya know, jump in a car, race and have fun for an hour or 2 with little fuss.
So, if that's what you like jump on in, if not, thank you for looking.
