With the Xcharger and automatic the 3.55's are better. The torque comes on so low in the Xcharger rpm power band that anything more is a little tough to hook up at the track. Lidio at Alternative Auto and I talked quite a bit about the gears and he recommended the 3.55's based upon the torque curve. It isn't like the centri blower where you need to get the rpm's up to make power.

4.56??? That is ridiculously steep for our cars (and any cars!). My dad's GT/CS has 4.10s and those are plenty. Still, Chandler from Brenspeed thought 4.30s were better....
Well for straight racing that is probably a better ratio for sure, Jim. Personally though, if I were to get an X, I would do the 3.73s because I don't run at the track, I just have a bit of fun around town (and I like my power down low).
