I'm about 90% decided to build my own front splitter. Unlike the FFR unit, it will be longer, to allow it to protrude further out the front and to allow it to connect up to the frame below the radiator. Also unlike the FFR unit, it will be flat and not have the raised middle section that follows the contour of the lower radiator intake section of the front bumper. It will be about 1/4" thick and will have a rounded front edge. It will be made of carbon fiber over a 6# divinycell foam core - light and strong, and it will be vacuum bagged for best strength, weight, and longevity. It should have a really nice look and finish to it.
Since I'm making one for myself, I was curious to see if others might be interested in one as well? I won't put out a pre-order page until I have the first one made and it turns out to my satisfaction. At that point, if all is good I will post pics. The only issue is that carbon fiber cloth and the right kind of foam for the core are very expensive, not to mention a time consuming build process. I won't be able to make one for less than FFR's unit, though mine will allow for longer stick-out, better frame tie-in, and be flat. I'm guessing it would have to cost between $600 and $1000.
