A friend of mine and I tried to measure some of the dimensions of the LX-250 from a photograph and our rudimentary calculations showed that the front and rear windscreen dimensions would fall just under the GBS minimum specs.
I am guessing from the photos of the M-6 Speed that these same dimensions would also fall short.
Is there anyone with either of these bodies and access to the GBS doco (its in the Roar Handbook 2008 page 54) who could verify?

I'll go grab my shell in a bit and get it measured up for you whilst I'm watching the NASCAR. Pretty sure theres quite a few bits where it falls a long way short of GBS dimensions
