CF will add about 12% to unit cost which seems reasonable for weight difference. The primary driver for me was weight reduction (goal is under 3,000 for entire car) so the cost differential was well in line with other measures. Having said that, the possibility still exists for doing them in fiberglass if the demand exists. My guess is that for not much more, most will go with CF.
Looking forward to hearing your announcement for general availability.
I have been watching the progress of this and eager to get in on one when the time comes.
I have looked at the Moshammer duck tail countless times but enough people have complained about poor fitment the requires modification to make it work, plus the awful square piece on the underside and it's a no for me. The Dissident duck tail is stunning but very, very expensive. The OEM Sport Design is nice but just a bit too subtle. This duck tail might just be "just right".
Once it becomes available or perhaps before it would be useful to hear specifics on install process (literal step-by-step instructions), how to disable the automatic wing deployment, etc.... I am also curious to know once you launch if you expect to continue to sell for an extended period of time or if it will be a one time run/for sale period.
Just back from Amelia. It was delightful. Did a demo out in the Porsche corral (sadly no recording but here are photos of development prototype:
Top and middle piece will be bonded together. Bottom piece fits in channel at rear base of wing assembly and held with existing screws. Don't worry, other photos much better. Components from side Underside of bottom piece showing air channel and mounting points. Bottom piece from side Attachment piece in place Rear of Duck. Hard to see but there is a hole to insert light module.
Weight (without light insert and two other mounting pieces) is 1564 gms (3.44 lbs).
Pieces go back to Charleston Composites for continued refinement tomorrow. Should be airflow testing in a week or so.
