Replacing roof with carbon/kevlar skin
Trying to figure out how to get rid of the sunroof...
I am planning on buying this carbonfibre/kevlar roof skin to replace the original roof. Just cut the sheet metal roof abt. 20-30mm (~1") away from the rain gutters and windows and then glue on this roof:

Make sure you give yourself enough working room to blend in the edge of the roof with the metal. (ie get rid of the step.
Normally when doing this it's a good idea to create a flat crimp lip (flange) around the perimeter and then lay the roof into that, it reduces the amount of filler needed to blend the CF to the steel. I am not sure how well a crimper will work given the slight curve of the roof etc.

Nice Juha! This is the way I'm gonna do mine. Saves a lot of weight and is actually pretty simple to do.
It's glued. They have adhesive for that.
Not that big of a deal really as some of the new cars have clued roof skins.

The adhesives available for this have incredible sheer strength. There will be no issue at all with strength, flex etc.
The CF roof will be just as stiff and strong and will be lighter than the steel roof, especially considering the steel roof has a big hole in it for the sunroof.

Hans confirmed that the method i posted is correct. He said it's best to leave 30mm of steel roof around the gutters etc. And to use construction adhesive like this: http://m3supercar.1g.fi/kuvat/993/GT...pg/_img900.jpg
Hans has fabbed many of the composite body parts for the teams racing in FIA GT with the '98 EVOs back in the day. So I'd assume he knows what he is talking about.
I also agree with Flying Finn; this is a quite straight forward job.

Thanks for the info Steven and Juha, you've got me thinking about this mod. I wonder if I can find someone qualified and comfortable to do this. I have been on the lookout for a early 911 non-sunroof skin, but they almost never come up.

Front fenders : Hahn GFK in Germany
Front bumper, splitter, banana wing: GT racing in US
Flares, side skirts: OEM maker in Germany through FVD.
GT2 tailbase: some company in Poland (bought it off of ebay)
I gotta say the FVD parts were the best composite parts i have ever held in my hand. He others were't bad either.
Hahn GFK is supplying the doors, cf rear bumper, roof etc. Like i said, they have made these parts for the EVOs that raced in the FIA GT series.
