FYI - a 6" bumper plywood backing attached to a 3" metal bar will not pass inspection since it's not supported along its entire length. For example, with a rectangular robot that is the max 28"x38", the opening can be, at most, the length of the edge minus 12". You can build a build that fits in the 28"x38" sizing box at a slight angle and use a marginally larger opening but you'd be building a very thin robot.

If Paul is right and your leading edges are small, the inspectors will give you a hard time and probably ask you to modify your chassis.

Better now than in 2.5 weeks.

Our bumpers are 5" wide each at the front, but to make ourselves legal we're bolting a 1' or so long piece of 1010 sized 8020 to the inside of the wheel assemblies giving us another inch on each side.

They look 3-4 inches long only because our flanges bend inwards on the drivetrain sideplates.
