I came back home from TMC Connect with preproduction betas of carbon fiber panels that overlay the B-Pillars. They are made of real carbon fiber with a protective flexible gloss overlay and a backing of 3M tape sheet to attach them to the B-Pillar. They were graciously provided by Matt and Roger Pressman of EVAnnex for me to test fit on my car. While Matt told me some final modifications are being made before production begins they were perfect as far as I am concerned. Installation is quite easy but must be done with care. Matt warned me that the 3M backing tape sheet is so sticky that you get only one chance to position it correctly. If you make a mistake, you will find it impossible to reposition. Here are a few photos of the panels and the installation methods I used to be sure it was in the correct position when I attached it. First a few shots of both sides of the panels. I prepared four long pieces of 3M blue painters tape to hold the panel in place while I attached it. I held the panel precisely in place then wrapped the tape around the B-Pillar to secure it. The white strip at the top of the panel is provided to make it easy to peel off the protective backing on the 3M sheet tape. With the panel in place I pulled the top third of red backing down with the white strip and pressed the upper section in place so the it was glued in place. This photo show the peeled backing squeezed under the panel. With the panel held securely in place by the upper third, I then removed the painters tape. Lifting the panel from the bottom makes it possible to then peel away the rest of the red backing. With the backing removed the rest of the piece lays nicely in place. Pressing the panel all over the surface secures it. For me this is a very nice complement to my carbon fiber spoiler, front and rear diffusers, nose cone, and side strakes.
