The more I think about it, the less I like the idea of a fuel cell in the passenger floorboard of a Miata. With the disparity of cars that enter enduros, there's just too much opportunity for a side collision that could compromise the cell, and the idea of 25 gallons of fuel spewing next to me while I'm flipping upside down is "unattractive"...

I think I'd pursue the idea of putting the cell in the stock location, as far forward and as low as possible, with the quick-filler in the stock location (remove the filler door).
