Whoever makes the tracks between these three groups really knows what they are doing. Most of these tracks are obvious choices, such as the tracks featured on the bullring website, and some WKC and WCR tracks.
One reason I do this is because it may be hard for folks to find the best tracks for dirt racing, including myself, so for those folks, i hope this helps. In my opinion, these tracks seem to really nail the fell of sliding a stock car around an oval, while this will never be anything like Dirtworks Designs for rFactor, as a NR2003S mod, I think it hits the spot quite nice when using the right tracks. I have a file list of what i shook down to what I thought to be the most 'realistic' tracks for the purpose of dirt racing in this game. So, I took about an hour, and tested about every track but 3 or 4 i think on weebly. So, lately, I've been toying around with some dirt tracks for this game, and I've found that a majority are quite hit or miss, and when I say quite, I mean that.
