Are extensions with bumpers after the start of the game legal

And you can't declare it part of the frame perimeter, since the frame perimeter must be composed of non-articulated elements—you'd fail inspection on account of <R12>.

Makes sense. So if we reduce the width of the extensions so that the pseudo bumpers do not over hang the frame perimeter it looks like we are in business.
