The carbon slicktop thread

[M3fanatic580]

Carbon roofs look awesome. Sunroof delete if you can afford it is money well spent.

ABS auto body is the only person I will trust for roof work. I purchased a donar e46 m3 because it had the OEM CSL carbon roof on it, Kevin who is the owner of ABS took on the challenge of removing a 15 year appoxyd roof flawlessly without a single crack or chip. Then he prepped it for my LSB CSL car , perfectly removed the windshield and aligned everything to spec. ABS AUTO BODY

You guys are right. I got work done at 2M.

I was lured with their euro headliner saying that they may have one available and if my car was in their shop, I could get it first before others waiting for it. Once my car was transported there, the story changed to how their mold is almost complete and it just kept dragging out since. After 2 months of waiting with no headliner, I just wanted my car back and then I posted my observations in my initial post. David was very pleasant to work with throughout the process and there was no way I thought anything could go wrong with all the carbon conversions they may have performed. I did have to press him a little to start working on my car and either he was very passive because he was very agreeable or I was just a fool. Likely, the latter.

Sounds about right. I didn't have this issue when they did my E46 but I did have an issue earlier this year where David @ 2M took almost an ENTIRE FUCKING MONTH to respray the hood and fender on my M2. Nothing but excuses and bullshit, and there were a bunch of things he didn't do that he said he would.

I cannot recommend 2M Autowerks anymore, sorry that you got tricked and BS'd.

Did you think about printing one in a few smaller pieces? I feel like if you could make it slip fit and use some sort of filler to smooth out the gaps, that might work for a piece like this.

That would probably work, but it would also probably weigh 10x as much as the stock one.

Posted a scan of a US slicktop headliner here in case it's useful: https://nam3forum.com/forums/forum/m...897#post317897

Seems like the euro headliner is the same, save for that bump in the middle. If you bring that down to follow the contour of the surfaces next to it, it should be the same.

It can be a future project/mold if enough interested.

I also think a CF exposed headliner could be cool with matte finish

My Karb roof has developed a orange peel texture. Is the fix just getting it re-cleared or will I have to apply a layer of epoxy?

Getting it sanded flat and re-cleared is probably the only solution. I would hope that after that, the finish would stay flat and won't texture again.

The genuine E92 M3 CF roofs can have topcoat failure where the coating peels off in sheets. Shops seem to be removing the old topcoat and re-clearing those roofs.

How many would be needed? Count me in.

To make a mold worth it, we need to make at least 10 parts out of it.

The topside where the clearcoat is sprayed. After some heat cycling, the clearcoat slowly goes from perfectly smooth to being textured in the pattern of the CF weave. From what I understand , they remove the part from mold, scuff it up, spray automotive clearcoat and then sand and polish.

Any suggestions on how to rust proof some of these drilled holes?

Is it as simple as a rust-oleum rust spray? ...or is there something thicker I can apply with a brush?

Wurth brushable seam sealer might be a good option, will also kind of match the color

[Gt4]

YES. Gt4 please make some headliner blanks. Let customers upholster.

This!!!!

Only thing holding me back at this point...

I may have missed it, but what do you plan to do about sourcing a slicktop headliner?

I got lucky and was able to find a UK Ebay seller to ship the headliner to the US. I paid him a bit more on top of the listing price for his trouble and about $400 USD to ship to the US.
