Ok, so i was thinking about this. I think i can build a basic metal frame that attaches to the axle, and the little air foily bit that hangs off the back bumper. V1 would be covered in Coroplast. If it offers gains, V2 would be covered in aluminum sheet metal, and painted either black, or the same color as the car.
For some reason it feels like i'll be increasing the wake though, and that there will be 'more car' that the low pressure 'wake' will be 'pulling' back.
also, if i can get some sharks with frikken 'lazers'...
