How does the M5's carbon fiber roof help with performance?

I've heard the M5 has a carbon fiber roof. How does this contribute to the car's performance?

Having a carbon fiber roof significantly reduces the weight of the vehicle, which improves its overall performance. It also lowers the car's center of gravity, making it more stable and agile while driving.

The carbon fiber used in the M5's roof is also stronger and stiffer than traditional materials, providing better torsional rigidity and enhancing the car's handling and responsiveness.
