Does the carbon roof have any supports?
Looking at that install of the CSL roof on an E46 M, it looks like that even for the E46 coupe (which has a much smaller roof area than an e90 sedan) BMW spec-ed a steel support.
Did you guys add anything similar to your carbon roof. Do you know if the E92 OEM carbon roof has a support? Given that your piece is bigger than the coupe item, can you explain how you guarantee roof integrity?
Piece looks amazing. Very interested in getting it for my sedan when it shows up in a couple months...
Thanks,
FZ
