But I do think if I were blinded and drove two otherwise identical vehicles aside from the roof, with decent seat time in both it would become clear rather quickly which had the pano.

Whether that has to do solely with the 50+ extra pounds sitting at the highest point and affecting CG, or whether the additional bracing used in those with the pano, or a combination of both, hard to tell, but I'd be curious if anyone else has had a chance to extensively drive both and has noticed a difference.
Just a guess but I'd say back to back, you "could" notice a difference, just like adding cargo, or different wheels, tires.

Would it make a difference in lateral G's? Probably barely measurable. Would it make a difference in lap times? Maybe by a pro to win races, but I personally wouldn't delete the pano sunroof just for a few 10ths.
PS: I did get a non-sunroof M2C but that's the more popular choice in that model. So therefore I wanted it in the X3M.
