Hi everyone, are the rivets in this photo factory original for a CSL please? I've found photos of other cars that don't have them, but they could be CSIs, which have a steel inner brace.
Door rivets factory original on CSL?

Looks correct to me. I thought there were only three so I’m not sure about that upper hole. Could just be that I don’t regularly see a stripped door. Also just looks like a rust hole. Verify with @CSL177 since he has a NOS CSL door.

Thank you, much appreciated.
No worries! @Markos is the one that originally pointed this detail out to me. One of those things that once seen, it's easy to recognize.
Hi everyone,
since I am just stripping my CSL doors I can show you how they look from inside and how the Aluminium parts are fixed to the steel frame by rivets and glue:
The upper part belongs to the aluminium door, the lower part to the standard steel door

Thanks for sharing. Looks like your doors have factory hexagonal butyl sound deadening. I didn’t think that was applied on the CSL. Learned something new.
I'd say glue as you can't weld a steel nut to an aluminum brace...
As tferrer said: on the steel body all parts are welded, on the aluminum they are fixed by glue or by rivets.
Not only the nut but also these parts.
On the left picture you see a strip of glue still attached to the upper part of the shell. This is to make sure that steel and aluminum do not get in contact. Shell and steel frame at this position are fixed together by clamps.
Note the white powder aluminum corrosion on the right picture

I think none of you've noticed what I'm about so let me show in color.
Both parts are the same but other sides. One is filled with a glue, silicone or resin while the other is not (or maybe there is much less glue like filler).

Perhaps the nut came loose because of the reduced amount of factory glue and the repairman said, I'll fix that!I think none of you've noticed what I'm about so let me show in color.

Hello,
now available again at W&N: "Set of repair panels for inner upper door left aluminium"

Together with the aluminum shell (which is also available at W&N) and a good steel door frame it will become easy now to put together a CSL-door!
Upper door panels for steel doors are also available now!

According to BMW catalog CSL doors are 4kg lighter than standard ones.
The door brake can feel a little relieved.
4kg is enough of a reduction to use aluminum hinges, which along with the doors provide a weight savings of 7.15kg or nearly 16lbs. It is difficult to shave 400lbs from fully furnished car but they made it happen with the CSL lightweight.
