If it were me, I'd be sure to print up a few cards that say "I told you so!", so when it happens at inspection (and it will), you can hand them out.

To help your kids manage the stress when they fail inspection, have them think of exactly how they are going to fix it, and make up all (or many of) the wires, brackets, and things they'll need to do it in the pits.
