You have my interest, but I would have to see a completed one first and understand the process required for the install.

 

I'm hoping to save 70+ lbs? I've read elswhere in the forums that the sunroof + tracks + motor etc is around 60 lbs, then replacing steel with carbon fiber saves weight too.

Even 50 lbs would be significant given the location of the weight.

As far as the exact steps/process goes, I'll try to have them write something up.

 

I was talking with a Rally shop on this earlier, they have done this on an Evo, they used a really tacky glue to install the cf roof on, said it would not come off unless you cut it out.

 

so would this replace the entire roof of the car or just some of the steel as well as getting rid of the sunroof? Would there be any way to keep the sunroof and just c/f some of the steel? I love my sun roof and every chance I get I open it so I would prefer to keep it if needed.

 

cftype in SD? i think you guys got this all wrong....

cftype specializes in CF WRAPPING (read their webpage)...im about to do this to my roof (i do cf work)
basically, they just lay cf on your roof and epoxy it for "cosmetic" reasons....Sinful Enhancements here in SD does that as well

how do i know? im friends with a lot of their teams members...

i could be wrong..but im 99% sure im not

seriously, you really think they would CHOP off your roof and put in a cf roof? the resulting loss of structural integrity would be ridiculous.

 

cosmetic cf is superficial and it's wrong.

I still don't understand why people are saying structural integrity, since your a frame and b frame is what supports your structure of the car. The roof is there to tie the b pillar and keep rain out of the car.

it would be rediculous to spend $1000 for looks that nobody could see half of the time,

 

I just replaced my sunroof with an MR panel 85 POUND differance...unles it's a Dry prepreg layup (tooling about 8,000.00 ) it will be heavier than the MR roof

 

number one- roof would probably be stonger if carbon fiber is done correctly- key word correctly. but not to trash your idea, i prefer engineers who work on ferrari's etc to do my roof, rather thatn someone to splash a mold off a design that was never meant to be cf in the first place. cool idea, not enough engineering.

 

Unless you removed a sunroof (which I didn't think you had) how the hell did you manage that Robi?

 

Complete frankenstein job cut the old head (roof) off glue the new panel in place...I am having to re-learn how to drive the car as the weight up top I used to use in some of the quicker trancitions (chicanes) but it is really alot faster in the big sweepers (don't feel like I have a heavyweight sumo pinning the outside front corner to the bumpstop...)

 

robi,
Do you have any pictures? How much did it cost you to do?

Thanks,

 

Did you get the MR roof from Mitsu? If so, how much does that cost? I hate the fact that my car has the sunroof. Completely pointless since I never use it.

 

the only reason i got my sunroof is that i didn't know at the time that it added so much weight...i'd be glad to get rid of it now as the benifits don't out-weigh the added weight (no pun intended).

and if i could get rid of the steel and save even more weight up top, great!

robi - i'd love to know how long it took to get the MR roof on in-place of the GSR one and also how much it cost total.

secondly, i'd love to have a WHOLE lot more info on the carbon fiber one that dyuyeno is proposing. pics of the porsche and a write-up on how they did it. also, a follow-up on the porsche...how's the roof holding up now? and any answer on how heavy the stock roof was compared to the CF one when the guys got the stock one off the car and into their hands? was it "WOW, what a difference" or was it "well, it's lighter, i guess"?

 

85lb saving is awesome, if I could find someone to do this for me, it definitely be worth doing.

 

I would still wont get rid of my sunroof. I like my sunroof. then again, i'm not gonna go full out racing with my car. I'll just loose some of my weight. lol
