so on a car that is mainly street use, with the occasional trackday....
that needs the sunroof removing and a steel panel is hard to get and costly to paint....
gluing on a carbon skin would be acceptable, when considering that i have a fully welded rear half cage with double diagonals? *which is tied into the B pillars
of course, i will check with my insurance first - another point.

I'd be more afraid of a puncture than strength. IE, if you hit a tree sideways, the roof won't stop a branch from going into the cockpit. If you roll it over, a rock will puncture the roof. I can tell you that simply hitting a deer with my race car destroyed a carbon fibre fender like it was made from paper.

I cut the entire roof off my car and replaced it w/an early non-sunroof roof. The weight difference was incredibly. Once the oe roof was cut we went to take it off and I swore it was still attached. On top of that I run a full cage...bolt in but full 8 point cage.
Geoffrey, I know strength in the rails, but my comment on rigidity was based on the word "roof" as I think of the entire roof that say Getty sells which would mean cutting off the oe roof at the A, B an C posts.
By the way, is your seam welding, etc. covered in your race car post?

Seamwelding is covered in the Racecar Project posts.
I understand your definition of "Roof", however, I think the "channels" are part of the chassis and not part of the roof. There is a large difference between the entire roof structure of a sunroof roof and all of the substructure required to support the sunroof and a simple non sunroof roof skin.
Tom's savings is with the removal of the entire channel structure along with the roof. I've cut several 964s apart as salvage and once the roof is cut at the a,b,c pillars, the doors won't open and the chassis flexes significantly.

Regarding LA964RS and yours words, I wonder why the older models roofs are lighter than my 1991 Carrera (non-sunroof) for instance? due to thicker steel? anti-corrosion treatment?...why!
