So thatís the list of materials, now letís get down to the actual lip. I chose something way too advanced for carbon fiber, especially since this is my first project involving these materials. The picture above is what I planned on, yet it turned out to be very basic and looks awesome in the end.

After approximately 30 mines of mooch up using masking tape and cardboard, to place a general picture of what I wanted on the car, I decided this would be very hard to replicate on CF material. So we cut back on the open vent area in the bumper and went with a low profile Sit Limited type CF lip.

After making a direct copy of my bumper on cardboard, I traced the pattern onto the foam board and started cutting and sanding; this was a short but important step that gave shape to the lip.
