The carbon slicktop thread

Epoustouflant Anything from Karbonius about a group buy on the roof?

[Cronenberged]

TC design is the first shop that comes to mind. Though I’m sure others are capable (performance technic, VTmotorwerks, edge)

Maybe DanAvoN7 would be down to tackle this?

The first company to perform it isn't far from the bay, Bees something is all I can remember they're done quite a few. There's also a BMW performance.and repair shop near there that would be good at it. They're known for some crazy engine swaps.

Actively reading through this thread. Lots of great info.

I will definitely ping Karbonius to see if a winter GB on the roof could be possible.

It’s on my to do for the PY.

That looks amazing man, start to finish how long did it take and what DIY did you use? Looking to tackle this on my own next year.

I had a lot of time to prep by buying all the tools I needed and had downtime and waiting because I was taking my sweet time and waiting for certain parts to come in I found out last minute


Part 1: Prep (3 hours) Remove entire interior, seats, pillars, moonroof, headliner

Part 2: Drilling out spot welds and removing roof (4 hours) Remove the 4 nuts/washers holding the original, roof rack in place. this makes it easier

Part 3: Prepping roof with sander or angle grinder with the right piece to make sure its all clean (1-2 hours)

Part 4: Install bow this can vary depending on what you do.

Part 5: Prep the roof to have the epoxy(i brushed on everything that was exposed metal and install the carbon roof with clamps (1 hour) I had time so I let it settle for 36 hours

Part 6: Put windshield back

Part 7: Put interior back (1-2 hours)



The waiting from step to step is what took the longest and the drilling.

I watched AJ Hartman's DIY and some Munich Venom and some others DIY on forums and IGs but I combined them all together and used what I wanted.

Where did all the potential carbon fiber group buys go? I'm back on the hunt for a CF roof for the race car.

Does anyone have experience with Aero Function AR1 carbon fiber roof? Weight? Quality?

All good shops. You can’t go wrong w any of them.

TCD would use something more race car oriented so it may not have the polished look and a nice thick clear coat but it’d have the weight savings. My car’s in the shop for a bunch of work including a cf roof.

Anybody know a good shop in the Bay Area that can or has done this?

Also did the group buy ever happen?

Found a crack in my windshield and I've always wanted a CF roof, so this might push me there.

I think if I had an AW/Silver/Black/IB I might roll with a CF roof, but for PY/Imola/LSB the roof body color looks better IMHO. Somebody posted some pictures of a slicktop conversion done on an Imola on M3F just before the site when down and it looks fan-fn-tastic.

Personally grown tired of the stark contrast of black trim (or cf) with light colors these days and do prefer subtle shades like a cf roof on a black car. Fortunately I don't have to worry about any of that because my car is sunroof-less from the factory

Anyone done the M4 style CF roof from Karbonius? Not sure how I feel about the look. Would be nice to see some pictures other than what they have on their site.
