Made from a 4x8 sheet of 2" thick pink foam board. I used thin plastic sheet cut into 1 1/2" wide strips. Cut into the foam board with a utility knife, widened out the cut a little with the tip of a pencil and stuck the plastic 1/2" down into the foam. Works great. Now I just have to paint it and detail it a bit to get rid of the pink.
We have 3 SE. Two I have trimmed the steering rack to give a little more right turning, one I have left completely alone. All three do just fine. If you pick the right line and don't oversteer the car you can make lap after lap without touching the walls. Lanes are 11 inches wide.
