They just started Class C fixed set racing. I am reading some good responses to it. I did spectate an Indy car fixed race a Pocono last night. It had some of the top dogs in it...Tyler Hudson and Tim Doyle.
They also have the trucks involved in the fixed races...looks pretty tempting to me. No need for pit stops because they are just half the laps of official races. I did some testing with the fixed truck this morning and had no problems controlling the car.
