The Silver State Challenge is one street race that I would love to do. Its not as long as the others. But its held twice a year and not too many cars finish in the upper classes. 90 miles of street racing no speed limits. The only speed limits is safety requirements. But then I don't think they pull you over for breaking your limit, just get disqualified.
Best part is you can run almost any car.
To run unlimited yor car needs to pass spec. and you have to have raced at a previous 150 mph level.
