I'm in agreement with robk. Even though I'm just getting started in USGT, I completely understand the "leveling the playing field" perspective. Yes, we can select from a wide variety of bodies, as well as what chassis we want to run. Yes, we can tune the cars in (almost) any way we want. Yes, we can even choose whether to give a vehicle more of a front, rear, or centered weight bias. But, in limiting other "variables" (ie. motors, ESCs, tires), makes it more about a driver's skills, and less about who can spend the most amount of money tobuild the fastest car, or using a faster 17.5T motor...or about a better-performing and/or longer-lasting tire. Just as in racing 1:1 cars, there are classes that specify certain things, so as to make it about what it's SUPPOSED to be about - the ability of the person behind the wheel. Remember "The Tortoise and The Hare"?
