What rear gear with T-5?
>I'm running 3.73's with a T-5...I don't know the first gear ratio for the trans, but it is very low with this rear gear...1st and 2nd gear runs out very quickly and I find myself running mostly in 4th and 5th with 4th the deep accelerating gear. Would I be happier with a 3.23 rear? I;d like to run in 2nd and 3rd on the street with 4th and 5th for the hiway. Thanks

1st 2.95
2nd 1.94
3rd 1.34
4th 1.00
5th .74 or .63 (depending on the trans)
3.23's work for me as you describe in your last sentence.

I also have 3.23s and a t5 and I like the way it keeps my rpms low on the street and on the highway.
