A CNC punch press would take about 3 minutes to produce the side panel. If the material was .060-.080 alum it would take about 10 minutes to laser cut a part.

A well designed sheet metal part with some folds could take a fraction of time to make and a fraction of the cost to produce.

Just some food for thought to keep costs down for teams with new sponsors.
Good advice.

I disclose I am employed as a design engineer for aforementioned company. I actually had all parts nested to the laser due to the reasons you mention. It was the president of my company who decided to switch the outer plates to the AWJ. But who's complaining?

I believe cutting four of the outer plates took roughly 7-8 hours in total. (!)

To cut the four inner plates on the laser took around 1.5 hours.

Outer panels are 2.8 lbs each and the inner panels are 1.7 lbs each.
