The carbon slicktop thread

[BMWahba]

for all of you who didnt buy the CSL roof rails, how did you guys attach the factory one from your car to the roof?

the metal roof has tabs that it attaches too and the CF roof now doesnt. Trying to figure how I can attach these things so they dont fly off.

I have this exact same predicament, some have recommended me to use double sided tape, but I tried and can't get enough contact.

where did you purchase your roof from? looks clean. is that 1x1 weave??

Its a Challenge roof 2x2. VERY nice weave and absolutely no flaws. Was pretty straight forward to install. I had the car repainted so it also has fresh clear coat and polish.

Cool mod, bit of a steep price for 52lbs and an inch of headroom, but I get it.

Definitely more than an inch, I would guess at least two.

Any decent body shop can do this. Its more time consuming than technically difficult. There is a lot of anxiety on spending this much money to rip off a perfectly good roof but looking at the roof everyday I have no regrets.

My Lang Racing Roof. Weave and fit is perfect, carbon is strong enough to stand on. Only problem is it did not come lacquered so had to do it myself.

Please share the details. Where did get it installed?

Hard to believe it's lighter-- the factory stuff is effectively weightless.

I could believe it works better.

have you ever held a magic eraser? the factory cotton jute is relatively much heavier

if you have the car apart it's worth your time to avoid buying this and instead use melamime foam to to absorb sound

it's slightly lighter and actually designed for it's intended purpose. the OE stuff is pretty much chopped up jeans and tshirts glued together.
4 sq feet is enough to insulate the roof

Never heard of DTM mentioned in the forums before, but they are really low cost at $695 for FRP and $995 for carbon and $150 flat ship.
