We have to make sure that the temperature is always in the right tolerances, that humitity is in the right tolerances, and that all the facilities are always working to perfect conditions. Because that is very very important for the stiffness of the car".
that doesnt say the CF adds rigidity vs. a steel roof... it just means its difficult to bond the CF roof so it performs as well as the steel roof.
