and don't think that you would have a problem with fitting 215/45 on your car, believe that the SVT sit 1" lower than a ZX3.

I'ts possible that that my math could be off ... but my numbers don't jive with yours ... here's how I figure the various Focus tire circumferences:
195-60-15 = 76.05"
205-50-16 = 75.06" (-0.59% compared to 15)
215-45-17 = 77.32" (+1.67% compared to 15)
205-40-17 = 73.67 (-3.13% compared to 15, -4.72% compared to stock 17)
