I have never had any track check for the trans shield, engine diaper, header tethers, anything other than dual return spring on carb, master disconnect switch, and sometimes neutral safety.
That ranges from a bunch of different tracks I race at in multiple states. Not saying it’s the right thing to do, but that shield isn’t stopping an explosion anyway. The intention is to put a trans blanket on it in the future, but I’m sure that will be useless when it hits the headers and melts lol.
