It is always funny to me that we discuss such useless crap as bolting or welding a bracket when we have a minimum weight. If you believe that 8 OZ up high is such a big advantage then carry on. Otherwise use some common sense and remove the allowed bracket and move on. Stupid to have all these sharp tabs sticking out everywhere in the car.

You might nit pick the rule and see it the way you want, but in the end it is irrelevant and makes IT look less attractive to future drivers. If the guy in the car next to me wins with one less bracket, I am OK with it.
