I really like this idea, and have money to do it. But, Im worried about loss of strength,
I have an 8pt weld in roll bar.. and SFCs but im still a little worried.

To me, a t-top design that is basically the same since the 70's (t-tops go into a big ugly bracket instead of a channel in the roof) doesn't flow

Since you guys pulled that stock roof panel are you going to use that as the base for the mold? Basically, glass around it or something? I have a wrecked 2000 Camaro in my driveway under a car cover that I am going to attempt this on. If it doesn't work out I didn't lose anything, but if it does I am going to transfer it over to my 95.
HOWEVER, DO NOT try to use that piece as a targa top. It will rip right off. Use it to make a mold and then make a targa piece out of a few layers of CF...

Windshield is fine as well. The a-pillars for it are the same as the convertible a-pillars. He has a 300lbs friend sit on his windshield and checked for movement with a micrometer, none.
Again, just to update the look of your car you do NOT have to cut the center bar out to use this...

If I do this, I'd definitely be cutting out that bar. I'm not worried about crash strength. I'm just thinking about everday strength. Is the windshield gonna sag. Seems like it would. What about the rest of the car. Will my cage add enough strength? If I do a wheelie. When I come down is my car gonna fold in half? ...

Wheelies and coming down? That's anyone's guess as you never know what will break when doing that...

Once he starts on it I'm figuring AT LEAST a few weeks to get it into plug state, then I have to mold it and produce first piece so basically I'm shooting for the holidays (Turkey Day) to be done with this one...

I second the windshield not sagging. The only way it'll sag is if you roll the car or get into an accident involving the A-pillar. The A-pillars are very strong. I have a Camaro that was rolled and it was a bitch to push the one bent a-pillar back up even with a good Craftsman floor jack.

Windshield definitely will not sag on you. Again, same a-pillars as convertible and even if you're worried they are somehow different Chris' car was targa'd and YEARS went by and no sag (he checked with a micrometer again).
Wheelies and coming down? That's anyone's guess as you never know what will break when doing that...

so i guess my car could be the guinea pig on how it will effect the with hard launches
btw mark how does it lock in place? just like the ttops do??
im sure if it does, you could probably add some extra carbon fiber in that area to keep the car stiff when its in place(for us guys who like to beat on their cars)
and well only an idiot would be launching his car with it off

It is second in line (first was the 2010 spoiler which is 99% done) so hopefully soon.

CF is lighter... Not sure where that was miscommunicated that it wasn't.
We're using CF instead of fiberglass FOR its strength. Being that there will be no center attacment point (and there is a low pressure zone there) we need it as strong as possible so that it can be held on by just the sides.
Luckily, I was around with Chris (Whistler) did all the testing on his and we have a starting point, CF.

I was never able to get the original back from the the last guy unfortunately so I finally gave up and am starting over...
