RE: Gears
To each his own.. If your driving highway allot, then go with 3:25 or 3:00 gears.. I myself like the light to light responce with 3:55's.. Below is a compairson of 3:25's and 3:55's at 60, 65 and 70 mph. The tire size used for this was 225 / 45 - 17
60 MPH
3:25 = 2579 RPM
3:55 = 2817 RPM
65 MPH
3:25 = 2795 RPM
3:55 = 3050 RPM
70 MPH
3:25 = 3010
3:55 = 3287
60 MPH
3:25 = 2579 RPM
3:55 = 2817 RPM
65 MPH
3:25 = 2795 RPM
3:55 = 3050 RPM
70 MPH
3:25 = 3010
3:55 = 3287

Ok, Im sorry, but 55-65 on the highway is grandma speeds. IT'S A MUSTANG. I wouldn't do anything to it, that would cause that. I like to cruise the highway around 75-85.
Just an FYI, if your going to go through all that work, go with a set of 3:55's. I just did mine and its fine on the highway as long as you keep it at 55 - 65 you're good.

Hey what kind of tranny was used to get those numbers? I have a C-4 in mine. I figured their would be more of a difference in rpm then that. Thanks for the posts guys this is really helpful.

Well guys I've pretty much decided on 3.25's for the simple reason that I have a 20 minute ride back and forth to college everyday and that they will give me enough pep to satisfy me for now. Thanks for all of the replys. I appreciate all of the help!!!!!!!!!!!![sm=hail.gif]

RE: Gears
sorry for the retarded question but i haven't had a daily driver car in a couple years. what is a "comfortable" rpm range to be running on the highway? i'm with you guys, i like the 75-85 mph range for highway speeds. sorry for the question but im used to my diesel powered f-250 and she doesnt like going much over 2200 rpm.
thanks,
carl
