I have an 04 GT with a k&n FIPK and Magnaflow Magnapack cat-back exhaust. My next upgrades are going to be a Diablo flash tuner and new set of gears. Im having trouble deciding what ratio to go with. My ultimate goal is to build a corvette killer. Im not sure if I should go with 3:73's, 3:90's or 4:10's. Suggestions would be great!

I have a 00 Gt and I just got a set of 3.73s(not in yet). It all depends on what you want to do with the car. If you are going to run an N/A set up 4.10s might be the way to go, and if you have an automatic I would get 4.10s either way. I have heard a lot of people say how much they like their 3.73s in their cars but most have a 5 speed. They also say that if you plan on having a power adder stick with 3.55s or 3.73s. Ill let you know how I like mine next week.

Thanks for the suggestions! you guys say 4:10's Im just wondering if it is too much for everyday use. How much difference is there from the 3:73's. Also how does it affect freeway driving?

wow not sure that'd be too good for a highway car. I'd say 3.73

4.10's unless you're adding a S/C down the line...then I'd go with 3.73's
