OK, I found a discrepancy...
Something about the tire size doesn't add up.
USDM Fit Base 175/65R14 -> 22.9" diameter
Worldwide Fit Base 175/65R14 same diameter
USDM Fit Sport 195/55R15 -> 23.4" diameter
Worldwide Fit Sport 185/55R15 -> 23" diameter
Does that mean that for the same USDM trans gearing (5MT or 5AT), choosing sport over base, thus a +.4" diameter (-20 revs per mile) means the speed will be 1mph higher than indicated on the speedo (Sport). It also means mpg can be up by ~1, and accel times be slower by ~2%.
Anyone else notice this?

I read somewhere that there will also be optional 16" wheels with 205/45/16 rubber.
As for keeping everything proportioned for speedo / fuel economy / etc....I would only assume that Honda would take all of that into consideration...
