In R26, it says the bumper must be backed by the frame perimeter at the ends. How do bolts outside the frame perimeter affect this? If we space the bumpers out, does the ends having a 1/4 inch gap between the wood and the frame affect the rule? Because if so, it seems like most kit bots would fail too, because I know there are bolts sticking out on the kitbot.

If you guys have access to a router or even a drill depending on how your bumpers mount, you can make small pockets in the bumper to allow the wood to sit flat on your frame. See R21.A

A. be backed by ¾ in. (nominal) thick by 5 in. (± ½ in) tall plywood or solid, robust wood. Small clearance pockets and/or access holes in the plywood backing are permitted, as long as they do not significantly affect the structural integrity of the BUMPER.
