Oh, yay! I think they should all do that. WTH is up with blocking the front wheels, watering everything down like a monsoon, AND putting some kind of pad under the tire? What is that pad anyway? Looks like a piece of steel of something. The whole setup seems to be designed to burn the tires off of wimpy-assed cars that could never turn em over on the street. How fun, huh? Complete nonsense if you ask me.
But what do I know? I'm just some grumpy old guy who rarely burns the tires and never tries to confuse the car by using the brake and gas at the same time.
