Fasteners extending outside the FRAME PERIMETER

The obnoxious part is that the axle bolts for many teams this year are not in the BUMPER ZONE and thus do not set the FRAME PERIMETER. If an upper frame supporting the bumpers and a lower frame supporting the wheels are the same width and the upper frame has no protruding fasteners the axle bolt heads on the lower frame will be outside the FRAME PERIMETER and will violate <R16>.

I was suggesting that a simple workaround if these lower fasteners are not declared legal through the Q&A may be to have identical bolt heads in the level of the BUMPER ZONE so they redefine the FRAME PERIMETER as you mention in your post. This vertical projection of this larger FRAME PERIMETER would enclose the axle bolt heads preventing the <R16> violation.

I'm hoping the GDC makes all this moot with an answer to 1771's Q&A, as this workaround is more like a loophole
