CF Sunroof Delete Questions

Right on, thanks! Looks like the white is discontinued, clear is available it seems.

Hey guys, what's the best sealing product to use for this job? I'm planning on doing this plus a few other interior projects in the coming weeks, and I want to make sure I have everything ready in time. TIA

I did a lot of research and came to this as the very best. I have 4.5 track seasons on mine with zero issues.

Something like this:

Basically you want something that is UV resistant, water tight, and remains elastic.

Permetex Ultra Black Might work as well.

Could also use windshield sealant but that stuff is kinda nasty to work with.

Dummy check: a slick top headliner WILL fit if you do one of these delete panels, correct? Are there any clips or shit like that which are different between sunroof and slick top headliners?

Yes the slick top headliner fits with a delete panel, that is my current track car setup. The coat hanger hook brackets are different.

I have an S2R fiberglass panel, which also fits like shit. I decided to wrap the roof black bc I didn’t want to deal with trying to seal the uneven back portion. Works fine for now and will be getting a CF roof eventually.

Hmm this is not a bad idea, didnt think of wrapping the roof after the panel install. I imagine it'll take care of the sealing/waterproofing concern and visually the gaps from the panel (though I imagine there will still be a noticeable dip around the edges). This is an option for me as the previous owner of my car for some reason had the roof painted jet black and its a bad job. So would temporarily kill two birds with one stone for me since I was looking to get the roof repainted down the line.

I think the key to sealing either roof is laying an uninterrupted bead around the roof before insertion. Then seal from the outside. I scraped the outside even (not over-filled) with a credit card leaving no holes/air bubbles.

My research said to use a combination adhesive/sealant.

I have never had a single leak.

This is the exact process I followed. Although I seemed to have left some air pockets that sunk through when filling from the outside. Nothing another hour of work won’t fix.

I had the unfortunate experience of testing its fit/seal in a recent downpour yesterday

Update, sealing is absolutely terrible. If going for one of the fiberglass panels I definitely recommend ones with the grooves like the carbon fiber panels. I really overlooked this when purchasing.

They can be sealed by heavily filling the gaps from the outside of the panel. That’s my problem since we’ve been getting terrible downpours for the past few weeks.

I still don’t think my opinion would change about doing this or a carbon fiber panel though. Since my final plan is a full carbon roof anyways. If you’re not planning to go to a full carbon roof, then carbon panel all the way.

Did you seal it?

Not yet, this was just test fitting for paint. Will seal it after.

I just picked up the fitment labs Fiberglass panel. Personally I couldn’t justify spending 1/3 the cost of a full carbon roof when I plan on going that route anyways. This served as a stop gap solution for me.

Fitment is pretty good from a far, I need to take it for paint now. Most notably, issues with the back corners and getting them flush. For $250 I am not upset with the product at all.

I also think I will have issues with getting a sealing surface at the rear. I know the thread is for the CF deletes. Figured I’d throw the other option in here as well.

Final pic is having the rear secured. Ignore the new bulges to my roof trying to secure the corners raised the center a little. Should be easily correctable but there is a lot of fiddling needed with this panel

Ah ok, interesting. Yeah i recall the S2R fiberglass panels were going for under $300, IIRC something like $279? That's almost half the cost of the AJ Hartman CF piece though, cant say its not a significant price difference. Unfortunately seems like S2R went tits up, and is no longer available

AJ makes all of his panels to order. Its a one man shop. I happily paid the premium over the other options to support someone who devs and races his own parts.

Checkout his youtube channel, lots of useful content.
