Swap out moonroof for OEM carbon one

Thats a good point. Well you may have to give me your friends contact info . My main concern is the adhesion process. Other than that it seems like its a cake walk

Just because the dealer might end up patching something together does not mean that it will be up to factory spec and last as long. Long time ago, before the car was released, someone posted saying he spoke to a BMW employee who works at the factory in Germany who said there is no sound replacement process for the CF roof. I have no idea if that is true or not. If you search the forum, you might find that thread. Also, BMW has major body work facilities at the ports of entry on each coast. Maybe, that's where these things are addressed if there is a need. Anyway, good luck!

Thats a pretty good point im sure something has happened to someone with an m6.

After all, robots are better at these high-precision jobs.

Yea i hear ya. I know what you mean about the body work. Nothing is like an OEM job. However there are a lot of people who can get pretty damn close.

Option number two is two just take the side roof sills off (wont affect the roof seal) to tuck in the carbon fiber sheet , and lay a one piece 1x1 carbon fiber sheet over the entire roof and either clear coat or epoxy over it similar to what 360 does with their carbon wheels. Obviously take off the the roof sills like I said, roll in the sunroof, and remove the front and rear windshield rubber seals. This way the carbon fiber sheet is hidden and tucked in underneeth.

If that's the case, why not just do the CF roof overlay? It's a lot cheaper and fully reversible.

Yea i thought about it but #1 is its 2x2 not 1x1. Also it comes out to about 750$ shipped from the seller on ebay which is a lot for an overlay. And a couple people have bought it on E90 and some say it started to bubble and warp.

You can order a 1x1 from that same guy. As for warping and bubbling, it really depends on how you care for it. If you leave it out in the sun to bake and expose it to the elements, it'll turn bad regardless.

True.....

I saw this on e90 its pretty cool if you do a carbon roof with a sunroof.

well my car is garaged so.....

Yeah, I think I've seen this done on E46s.

That would be pretty awesome if you did a carbon fiber replacement roof with a sunroof and used that ^...... that would be pretty cool. I would almost seem like a OEM carbon roof then hit the switch and its a sunroof lol

i wouldn't mess with it ... my friend took his e46 m3 to EvoSport and they did that job for him ... well about 1y later it started to leak somewhere i think ... when he took it to another shop they discovered that the job was crappy and everything was very rusty ...

it was all over the internet ... i saw his car in person without a roof and it didn't look good

Yea thats why i would only have a BMW body shop do it in the recommended factory specs.

Yeah, higher production costs should make up for the fact that the lip is less than 1/10th the product.

The M coupe crowd removes their roof panels to replace with carbon ones. The process for the E92 would be similar, I think.

Factory roof panel remove & replace instructions:

This sounds like a serious undertaking with a lot to potentially go wrong either during installation or, worse, down the line...I'm curious to see how it turns out if you go through with it, but its a big risk.

I don't get it! All that money spent on buying an M3 and now you're gonna get someone to cut the roof and put on a new one! What's the point? Have you ever thought about what permanant damage you could potentially be doing? How about future trade or resale in value? I mean, it's not like you're doing anything original to the car that can't be had from factory.

Just trade your car in for one with a CF roof from the factory and be done with it.

Yea i thought about that but then i wouldnt have .9% financing

Obviously i wouldnt just hack away at my roof. Its a 70k car.

My point was im sure m6 guys have got into a wreck, had a leak, etc. and im sure there is a factory procedure to replace the roof.

So your saying if something happens to someone with a CF roof they are screwed and their car is totaled?

Looked at the book today. It's a 26 hour job. The bonding kit and everything else will cost about 400 bucks. If people have been doing this on E46 M3s, Z4M and the like, I don't see what the big deal is with the replacement. Just find a COMPETENT body shop.

By the way, the CA route is a no go for keeping the sunroof. I don't have an explanation from them yet, but I'll ask them.

I strongly agree. Don't hack up a new car. You will lose far more in resale than the low finance rate will save you.

I wonder what a buyer would say when the spec sheet shows sunroof but the car clearly has CF?

@Kev, of those 26 hours, how many are curing and how many are actual labor?

I have to look at it again. I think curing is overnight. The labor quoted is the standard in the bible of body work and doesn't including curing time. It's purely labor time.

Um, removing headliner and BOTH windshields? My previous car's (a Mini Cooper S) exterior roof got damaged due to a break in (one week after I bought it), so the body shop had to have the sunroof removed to repair it. They took it to BMW of Honolulu to remove the sunroof. What happened next is the stuff of nightmares.

In the process of removing the sunroof, BMW caused I would estimate $7,000 worth of collateral damage in the interior/exterior of my car. The damage ranged from punctures in the leather seats, scrapes/scratches on almost every single interior body panel, scratched tint, broken interior trim pieces, broken clips, loose bolts, crooked headliner, layer of dust throughout interior, etc....

And that was just the interior. They backed into something, scratched the bumpers, exterior trim pieces didn't fit good, etc. Apparently they were hoping I wouldn't notice the several thousand dollars worth of damage because they didn't say a word when I picked it up. To make a long story short, they ended up replacing all of the items they damaged, which was cool and it all worked out in the end.

And keep in mind this was the DEALER that worked on my car, and they ONLY removed the sunroof. Can you imagine what MORE is involved in removing the entire roof??

Now my experience was probably far from typcial, but even if 10% of what happened to me happens to you, you will not be a happy camper.

The decision is yours my friend, but make an informed one. And remember, if any collateral damage happens, the insurance company will not pay for it.

That sounds terrible. That'd be enough right there to convince me otherwise!
