If were talking cheap racing dollar for dollar spec Miata cant be beat but who the hell wants to race one of those.
No offense to the Spec Miata guys. Those cars can lay down some quality times for what they are but lets face it. We're American Iron guys.
Speaking of.....another great NASA class but once again......if we want to race cheap dollar for dollar NASA CMC cant be beat. Maybe not as much power as we would like to lay down but the reliability and maintenance costs are a bit more achievable if you would like to complete a full season in a racing series.
EDIT: Trying to imagine racing something that only puts down 230 to the rear wheels and weighs around 3200 lbs.
