    Interest in a carbon fiber roof group buy?

    I’m in a mood to curate! Let’s curate! And I’m not suggesting to do a group buy and charge a price that is more than what a roof normally would go for. 🤣🤣🤣

    Seriously, got the process down so I’d like to advance my composites shop. Enter a carbon roof group buy.

    Is there interest?

    5 roofs - $950 each
    10 roofs - $800 each
    15 roofs - $650 each

    $500 deposit. All roofs will be 3k 1x1 carbon outer (same as the CSL) and a 12k 1x1 inner. Weight will be about 6.5 lbs. There will be no UV protection. Recommend clear coating for a street car. There may be minor surface imperfections that can be fixed by clear coating.

    Shipping is about $250-$350 depending on location. If there are a couple in one area, I might be able to send to a freight terminal for pickup.

    I can make a roof in a spread tow fabric on the outer and inner which is 5.4 lbs - 1 lbs lighter - cost is $200 extra. The fabric will have imperfections, just the nature of the fabric.

    This is not for you if you want ready to install for your cars and coffee event.

    *******UPDATE*********

    I added up the costs and good news! I can lower the price.

    5 roofs - $800 each plus shipping
    - 3k 1x1 plain weave - same as the CSL roof
    - 12k 1x1 weave on the bottom (the individual threads or tows are a little bigger)
    - Final weight will come in around 6.75 lbs +/- .25lb
    - I can do something custom - will cost extra - which can include a 2x2 weave, spread tow, make it stiffer by adding a layer
    - Must be a forum member with a couple of posts to participate

    Step 1 - Send a $600 deposit with your cell #. I provide updates on the progress
    Step 2 - Takes about 2 weeks for supplies to arrive
    Step 3 - Wait approx 1 week until I ship the first roof, Approx 30 days until I ship the last one
    Step 4 - Send the final $200 plus shipping. Waiting on a freight quote - might have to pickup at the closed freight terminal or pay additional to ship to your door. I will work with each individual to minimize the cost and inconvenience
    Step 5 - Receive the roof

    The goal is to get the roofs in everyone's hands 30 days after I receive all of the deposits.​

            Will the roofs be domestically produced (US-made) or sourced from an international supplier?

                Is the spread toe more ridged? Are you going to recreate the cross bar as well? I am interested depending on timeline.

                  The spread tow is stiffer and has a better resin ratio - meaning the carbon content is higher which reduces weight. The downside is spread tow will never have perfect cosmetics. Really more for performance - ligher and stiffer. The roof with the spread tow came out to about 1 lb lighter vs one with a conventional 1x1 weave that you see on the CSL roofs. Similar stiffness but the panel is thinner

                  Takes about 1-2 weeks to get a single roof done, really depends on how long it takes for materials to arrive.

                  I can make crossbars...would need a demand for it. Guessing that would take 2-4 weeks to get that done. Probably be about $300 ea for 5 parts.

                            A steel OEM roof is $2400. It can be done, need 5 people want to pay $1500 each up front and wait 3-4 months for a wagon roof. Or if someone has a dent free non-sunroof wagon...I can pull a mold possibly without damaging the paint.
