That roof air deflector is part of my other mod. Its more for FE on the open road. Its inclined to be the same angle as the rear window (-23deg) so as to reduce wake size. Its a wood-glass fibre composite with lots of Bondo right now and its not pretty. So don't ask me for more pics. The combination gives me better FE in urban and hiway conditions.

For the rolling eyes; the car was never built for economy. Its a limited edition unit meant for cheap fun on the twisties and track. And it still is.
