    Well I got the 3.25 diff in and it made a big difference over the 3.73 Thanks to all You R3V's dudes that gave me advice on what to get, and where to find the gear set, and for Your answers.

    Now I can see why some would say the 2.93 would be good gears.I am 70/30 freeway most of the time, so 3.46 was not for me.When On the freeway I think the 2.93 would be the cats meow, however in town not much fun. So over all the 3.25 gear set is the best for this car and driver desired result.

    After having swapped the Differentials ( DIY easy) I will be looking to find a 2.93 diff as well , then I could swap them from time to time, ( say long trips, and Far away projects blah blah blah. If gas were to go back over $4 a gallon then the 2.93 diff could be swapped, in like 2 hours. Overall goal before the swap was good performance and good gas mileage.

      i swapped from a 2.93 to a 3.15 (95 M3 guts) on our ETA and it worked perfect. Does no one run a 3.15 around here?
