The short answer I think is that you'll want more gear once you get
out onto the track. In my 00' GT the 3.27:1's are ok but in lower
gears take more time to come back up to torque peak. I have 3.42's in
another car with much less power and coming out of the corners I get a
better pick up than with the Mustang. Both have the BW T-5
transmission.
