A while back someone posted pictures of Masami holding up a red anodized SD CGM. I thought it was a custom job, but looks like it will be a production car. Cool.
Randman: You're right, double topdecks rule!! (for carpet)
wcoyote: The graphite gear boxes are much stiffer (material), and they stiffen the overall chassis also. I've also found that using the standard motor plate rather than the RS one helps stiffness. I'm now using the black chassis (not RS) for the same reason.
