One of the reasons I went with 3.73s was because I felt I would still be able to use 1st gear. If you ever think you'll resell the car with the 4.10's installed, you might want to reconsider. Also, performance wise you might see diminished returns because 3.73s and 4.10s seem to get about the same 1/4 mile times. No one has broken 13s without FI that I know of.
Another good thing about the 3.73s is that you can still get 28mpg on the highway if you're careful. With 4.10s you're probably in the 24mpg range which defeats any advantage over buying a GT.
