Wow! 4.81:1 rear end is going to be screaming when going down the highway! My Focus has 3.51 (or so) "rear end" with similarly sized tires and I feel that's spinning way too fast going down the highway.

4.81 are dumptruck gears - the only vehicles I've ever seen with that type of gearing are trucks for pulling or trucks/jeeps with large tires.

It'll get you a good 0-60 time, get you out of the corners on the track ... but not help FE that much.
