OK. Here's one version that may be more clear. We mocked up cardboard as the actual bumpers. Our mentors are reading the rules like R24 and Figure 4-8 as being top views specifically and that leaves wiggle room for what you see from the sides. Example, the top area that is decidedly less that 8" is ok, because from the top view the bumper does extend 8". This is an area that we are arguing about. We also have a mockup version where that area is filled in, but our bumpers will be frickin' enormous! LOL. The red outlined bit of aluminum plate will be removed, and the metal edge will be behind the wheels from the front view, behind bumpers from the side.
