3.90 rear end gears

[Kryo-Genik]

Is anyone running 3.90 rear end gears on their car, especially anyone running with an auto?
Im tossing up either 3.73's or 3.90s and 4.10s dont interest me to be honest. this go around I want to try and keep a good balance of mpg, lowend grunt and top end. no matter how i look at it im taking a hit on the big end with a gear swap but the above two gear sets are what im interested in

Works for me...

Actually 3.90 does work for guys who want more gear and don't want 410's you can play with wheel size...Power adder needs less gear...and n/a in my opinion 373 are not enough..

There's hardly going to be any difference at all, actually less than 5%.
