You'll haveta change the gear for the speedo. It's a sensor that plugs in the tailshaft of the transmission. Going to 4.10s will probably put you at the highest tooth count gear there is (23t I believe) and that gear isn't claimed to last a long time.

4.10s are awfully steep for the street. But in a NA 3.8 would probably be ok.

Plan on getting a custom driveshaft (like the MMX ones). The stock one will not like being spun that fast (you'll have a big vibration at speed).
