I think that has no sense too..some are not that good to that, and that is not even a point. That's the good of the game too, you prepare your car for race, cause a set can be good for me and not that good for you.
It don't have to be with real nascar types, the idea was not spend money on a nascar game, just a addon with 2 or 3 car motor types and a oval track or two..like bf1 release or something like that.
I think that nascar races would be cool, for me it's cool to race on oval races with many people, with colisions fixed i think that can be fun.
Please give your advice
