Shaft slop help?

This may not be the best thread to ask this, but at least it's about West Coast Drive. How do WC drives comply with R26(c), "the BUMPER must be backed by the FRAME PERIMETER at least every 8 in"?

Usually people put wide stand offs between the wheels less than every 8 inches to act as the frame perimeter.

Now let me ask a question of the OP. I think I understand your set up, but just to clarify, from the outside of the bot in it's wheels, pullies, aluminum tubing with hex bearings. If this is the case why are you using hex? You could just use dead axles and bolt the pullies right to the wheels.
