actually he was talking about SCE or Stock Car Evolution... however I'm sure Zippy and the boys at TSF have that info too...
sorry, I absolutely was talking about Sim Factory and not any mod like the ones you mentioned or something like vhr maybe. Pretty certain any info or details obtained in those would be light hearted or dated or even from under rated teams with limited expertise. People can say a lot of things are real or from real teams with nothing but words, but with TSF it's plainly clear in all their release notes, website and other areas of racing who they work with, where their info comes from and the engineering companies involved.
Shoot many of their drivers have championships already Ty and Austin for one. Minus IR, over the past months and years we have seen Jr, Kligerman, Logano, Allmendinger, McDowell, Clements and others in there or contributing too with broadcast races and such.
Not sure they have the Goodyear info like they do with Hoosier though, but since Hoosier was used for years in Nascar, and to this day when teams test they use Hoosiers too I heard, then I believe their releases will be the most accurate on the RF platforms. They are also partnered with ISI and I expect things are coded entirely better than modding could be too.
I was wishing you luck on GoodYear info because its been said even teams in Nascar don't get the details so it's pretty certain modders won't. just a fact really. But weirder things happen

*still like the start on your model
