There should be three classes like in sports amatuer, minor and Pro. You should have to demonstrate that you can compete in the lower level and work your way up. All of these different classes pertaining to motors is just sickening. Group the motors according to class. Amateur-27T. Minor-19T. Pro-whatever you can get to go fast 7.4 volts and less. With the breakdown in tires, car weights, type of motors, age groups yada yada, waayyyy too many brackets within brackets. If one cannot compete, then obviously, they will have to step their game up and work at getting better to rise to the next level of competition.
