Shafts were 7075 1/2 hex.
Sloppy is probably the wrong description, more flexible than anything. The top of the side plates had some decent flex in direction changes.
I like the suggestion for removing the upper inner support, ithink that could easily change depending on the game and mechanisms required.

Since it looks like your axles are supported by the lower side tube, they may bind in the bearing blocks and/or cause the robot to not drive straight.

That's a good point, it would help to add some reinforcement to support the lower beam alignment.
