Bracket racing anything slower than a 13 sec car is ghey, I will give you that.
BUT, bracket racing itself is not ghey. To build a fast car (10s or better), and to have it dead on consistent enough to win events, is MUCH more difficult that dropping off your ________(insert American Sports car here) at your local shop, like __ __ __ (insert your favorite acronym here) and pelting it with your credit car until it blings out of control and makes the power you desire.
I am not a bracket racer, but I am realistic. It is harder to build a Great 10 sec bracket race car than a 9 sec _______. Furthermore, if you are not a good driver, your bracket racing ability is hindered more, while in a heads up race, your can bog the launch or fall asleep at the light, and if you have the power, it will not matter in the end anyway.
