You could use the 'Aerodynamic Streamlining Template Part-C' to help with the dimensions of the spoilers.
----------------------------------------------------------------------------
As to the rear spoiler,the police,or vehicle registration officials may require a special permit.
In one of my books about Porsche cars,evidently,when the first whale-tail rear spoiler appeared on the 911 Carrera,a special permit was required,as the government considered the spoiler to be a safety hazard to pedestrians.
The next year,Porsche introduced the rubber-edged whale-tail which offered no additional risk to pedestrians.
Expensive,oven-baked rubber components would probably be beyond the scope of do-it-yourself streamlining,but there may be materials available to you which could be fabricated.
Also,a master male mold (plug) could produce a plaster 'splash' from which low-density polyurethane foam could be injected into and then covered with a weather-proof skin of epoxy or conventional polyester fiberglass resin.
If 'struck',the spoiler would shatter,perhaps with minor injury to an individual,but nothing 'serious.' Just thinking out loud.
