M2CS roof has plain weave on top and bottom, using two different types of weaving structures. Top is a UI tape (unidirectional fibers measured in the thousands) laid in a plain twill weave, bottom appears to be a 3K UI (much finer, denser form, being substituted for the cross reinforcement braces)
M2CS roof is as much part of the chassis as a prosthetic limb is to our bodies.

"For the M2 CS, the Germans developed their own unique roof, which is a structural part of the bodywork! This is different from the way aftermarket solutions are available in the market, or even the M Performance solution"
Lots of info on this.

This has the additional effect of enhancing acoustics, both inside and outside the car. And dispensing with the customary roof bows and insulation also saves weight. Together with the lighter bonnet, this serves to lower the vehicle’s centre of gravity, resulting in even better driving dynamics."

Replacement for it is certainly not easy.

No one's talking about the chassis?
