I have read so much about guys using the 2.47 ratio I wondered if anyone has used the 2.24. Every one that has tried the 2.47 loves it so I wondered if the 2.24 would be too high a gear ratio or just a little more of a good thing. According to (I think it was) brian carltons formula the 2.24 with 28" diameter tires would put my engine rpm at 2190 at 75 mph. I am impressed with the power of this car in all the conditions I have driven it at. My crazy wife has managed to get across the top of vail pass at 85 mph with 3 kids and all the crap that goes along with them so power does not seem to be a problem. And it gets 23 mpg city/ highway driving combo which seems pretty good considering the way she drives.
