I get that, but there was already a fledgling class of GT12 forming in the midwest based on the GT12 class in Europe, which utilizes less sophisticated chassis, narrow rear tires and runs a 13.5 motor. Calling the class you guys run "GT12" is akin to me taking a top-of-the-line touring car chassis, slapping foam tires on it, dropping in a 10.5, mandating that you can only run a body based on a real street vehicle and then calling that class "USGT." Would be pretty confusing considering there is already a class called USGT based on quite different specs/rules. Again I get your class and its lower running cost compared to 17.5 GTP 1/12th scale... and if it's popular/growing the hobby then more power to you. I just think it should have been called something other than "GT12." Spec-12 or Touring-12 perhaps.
