Just found this how-to

It was done to a BMW M3 but pretty much should work out just the same!

Who's going to be the first one to do it and make a Cobalt how-to?

the drool is dripping...

I just emailed the guy re dimensions. I was gonna make one on my own but if its close id rather buy this one

 

if he removed the sunroof assy. i wonder if it reduces the structural integrity of the roof. Before attempting, id would personally look at what a non sunroof roof assy. looks like. I know on Chrysler products, the sunroof assy. crossrails replace the stock ones.

 

what if you kept all the sunroof stuff and the cf just replaces the glass...that way you can still open it.

 

would be sweet if it was functional... I hate the glass but love my sun roof...

 

id be pointless, the glass only weighs 10 lbs at the most. its the guts that weigh alot.

you would be better off just having the glass super tinted.

 

oh Im very aware that the glass isnt the heavy part. I bet cf would be alittle lighter, but the main thing is....it looks a shitload better!!!

 

100 bucks says it leaks.

 

the guy got back to me and didnt really give me accurate dimentions so i guess im going to have to find myself a few bimmers to messure since m3, e36, e46 are all different

 

you could put the same seal that goes on the glass on the CF one.

 

you do realize that water does make it past that seal. Thats why you have drip trays and drain tubes in the sunroof assy. Watch the sunroof next time it rains harder than a drizzle, water comes in.

 

hold on, wait, why are you measuring BMW's?

 

I know that their are drip rails. Thats why if you just replaced the glass with CF, it should work just fine.

 

I like my sunroof too much to do this.

 

The guy who makes these is on ebay and makes them for 3 or four bmw models only. Maybe one will fit but i have a feeling ill be making my own lol

 

it would never stay on, if even alittle air got under it, it would fly away. Its a good idea, but not worth the time/money.

 

oh ok, I was lost for a sec

 

to each his own sir

 

yeah, what do i know, i only install sunroofs for a living.

 

So what another affordable option those of us looking to lost some weight up top / remove the sunroof?

 

*claps out loud in admiration*

 

just wondering, but why would it fly off? They are bolted to the tracking...

 

my advice. don't do it.

weight saved vs time/money/effort spent. is not worth it. the real way to do it would be to get Crawford Composites 100% cf roof. or swap roofs with a non sunroof car.

i don't see a problem in doing what this guy did. however once you get to installation and making sure everything is sealed and fitting right. you are going to get stressed, frustrated...and give up. except instead of just being able to give up you'll have to reinstall everything, hopefully you don't break anything in the uninstallation process

 

The problem is you want to maintain the structural integrity of the roof. the only way to do that is to weld in cross supports where the rails for the sunroof were, that hole will flex crazy without any kind of support, that BMW in the picture would need an " x " welded on otherwise during a crash, the roof may just come straight down or during a roll over. Yes, im just a lowly auto tech who installs accessories, but I wouldnt **** you guys. If you guys dont want to take my advice, thats fine. The best thing you can do is just weld it up and hope for the best if you want to save some weight. The heaviest sunroof i have ever put in was in a Durango and the entire assembly including glass didnt weigh more than 35 - 45 lbs.

because the Carbon Fiber, while strong, is thin and would be prone to tearing, you would have to graft the metal frame of the glass for it to stay on. Its the same reason you are suppose to use hood pins when you install a Carbon Fiber hood, the bolt holes for the latch will just rip.

 

Thanks for the heads up mopar!...sometimes I get a little to excited
