14" with low profile tyres would give you an even higher effective final drive ratio, but will also lower the car, reducing ground clearance. It's probably a good thing, then, that you can't get them! Lowest profile tyre I've seen for 14" rims is 55%, in a Toyo T1-R.
I'd go for 15" BBS - cheap, plentiful, easy to beat back into shape (!), and no problems with tyre availability.
