I would do 3.91 gears, for the money going from a 3.45 to a 3.70 isn't worth it.

I did 3.91s in my auto a few weeks ago.

I want to put a 3.9 or a 4.1 rear gear, but I want to keep the car with the good MPG it makes... I was thinking how hard and expensive would it be to change the size of the 4th, 5th and 6th gear...
(as of right now I use 1-3 for fun and just acceleration, 4 for driving in the city, 5 for driving on a higher speed limit still in the city, like 35mph, and 6 for highway)
I know jessrayo has swapped some of the gears in his transmission for ZR1 gears for his mile events. It is possible, but I have no idea how costly it would be. I would assume it would be in line with the cost of a transmission rebuild.
