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.
Evan,

6061 sheet stock comes in different tempers. T0 to T6. The T0 temper will bend easily. Heat treating after the bending process to get the part strong and stress free.

The T6 temper will crack if the radius is sharp. Another way to bend 6061 T6 is with a wrapper. The wrapper will make a large radius using sharp 1/32 inch dies.
