Doesn't matter if you have a 5AT or 6MT, I went from a 3.5 to a 3.7 and its definitely noticeable. The higher the number the shorter the gears (quicker acceleration). However, going with that high of a ratio may mess with the car's systems. So far I have not had any problems but I didn't change the ratio too much. Your speedometer will read faster then your actual speed as well.

My current diff came off a G37s sedan and required no fabrication. Some will have an extended pinion shaft and 3-bolt flange but its not hard to make these work on any G35.
These threads have the info required:
