I am surprised that your shop was set up to bend 6061, since most sheet metal places I've worked with heavily encourage 5052.
Regarding the flange, I suspect your shafts will be enough support considering you'll have bumpers on the chassis during competitions. The only scenario of concern would be a point load low on the side panel in between shafts, and that's going to be hard to do with a flat field and bumper-to-bumper contact.

We routinely bend 6061 in house as well, and just use larger bend radii to avoid cracking.
