I love it. Its good to see an "out-of-the-box" solution!
There are hard stops for the travel on all of the wheels, and travel can be limited without much trouble. I believe the largest amount of travel for a wheel on the rocker is just under 2". The nature of the rocking mechanism gives the wheels a lot of travel relative to each other without moving the frame very much. (If we lift the front wheel 3" off the ground, the frame only raises about 1.5")

We're intending to show the inspectors that the robot will sit on flat ground with any orientation of the suspension and keep the bumpers within the bumper zones. This should satisfy R22 without question, but we'll also bring our team's best lawyer just in case.
