Go to Post But please take into account that each year, the GDC has to come up with a rule book that will spend the next three months being picked apart by 40,000 of the brightest, most creative minds on the planet. I think they do an outstanding job of it. - dtengineering [more]

Re: Bumper height

Is that rule hard set or can we put it just 1" or .5" off the ground? Obviously ground clearance is ideal, but we want to make sure the bumpers dont break off.
Ah, sorry, I missed that (we didn't start our bumpers yet).

I don't see the rule changing, so you should start accommodating it.

The best I can think of is to make some kind of metal C-Channel or bar slightly elevated from your C-Channel perimeter that you can mount to the center of the bumper to meet the ground clearance rule.
