Your preaching to the Choire, I have been wanting one for a year. I was told, the bends are so sharp it is extremely difficult to bend the carbon fiber when molding. The only one I know makes them is Trufiber and they are out.
I just installed Trufiber front CF dash, (dual gauge) and CF A- Pillars. The pillars are pretty hard to install. I am now having "ALL" door switch panel bezels, window panel, Door Unlock Handle and the door hand grab handle made right now from Mustang Carbon Com. The guy did say he is a perfectionist and will not be like some of the cheap looking China made Bezels, panels. When he gets them made and sent to me, I will evaluate the quality, finish and fit. I like the 2x2 CF twill gloss finish. I also have Anderson Co.posite, Shelby GT350R CF spoiler, Rear lower CF Quad Diffuser, Side CF Rocker panels being made. 8-16 weeks.
full door panels?! Canāt wait to see that. How much is that running you?
I agree. On the doors,I meant to say Door window switch panel/bezel, Door handle latch with memories button option, the actual Door handle lever, and the door grab hand bar cover. Not the entire inside door panel assembly.
I ordered from them last February. Spent about $1100. By April, I was getting frustrated because I had no info on shipping. I emailed and threatened I would get my credit card company involved and within a day, i got an email saying a shipping label had been created. Of course nothing got shipped. By June I just called credit card company and got money back.
Curious to see how this turns out for you. I was looking at Mustang Carbon as well but I want to go with the matte finish. I reached out to the guy and he said due to the process for matte finish he only does a big batch of pieces. I didn't want to spend a few grand without seeing some examples.
Well, I just emailed him asking for an update. He did tell me he makes his own carbon fiber bezels, panels here at his shop. He did tell me it would take around 8-10 weeks so we are still good on the time.
What the heck is the difference in the two 
Most likely itās the amount of time invested in designing it. Trufiber had to start from scratch so their cost to profit margin is a lot narrower than ACGuys I need some carbon expertise. Iām thinking of doing a 350R Carbon Spoiler. Iāve narrowed it to Anderson and Trufiber. Anderson is 1300.00 and Trufiber is 2900.00. Anderson says theirs is made off 350R tooling. Is there a 1600.00 quality difference
Just a guess. They make the CF parts for the GT500. I donāt know if they made the original wings for the GT350R but if they did it makes sense why they are cheaper.
So on one hand, Carbon Cartel offers probably the neatest/most well-done interior carbon fiber pieces you can get for a Mustang...
