    I had 3.73 in my fox with a z spec trans and still felt like I was shifting more then I should have
    If I was to do it again I would go 3.55

    I did some more homework

    Overall first gear ratio (x * y)

    Z w/ 4.10 = 12.05
    Z w/ 3.73 = 11.06
    Z w/ 2.73 = 8.05 < Current

    T5 w/ 4.10 = 13.73
    T5 w/ 3.73 = 12.56
    T5 w/ 3.55 = 11.89
    T5 w/ 2.73 = 9.14 < Stock

    First gear with 4.10's will be like between 3.55 and 3.73 in a T5... I had 3.73's in my 86GT, it was fun but I could have had more gear... Ideally I'd go with a 3.90 lol

    I'd be 2500rpm @ 120kmh (5th) and 2000rpm for 100kmh in 5th... according to calculators online. But in 4th I'd be at 110mph at max RPM for my engine...

    With 26 inch tall tires 373s your will be happy with results. I have 28 inch tires and use 430 gears but probably put 410s back in this winter.

    I have to agree with Ed - I'm partial to 3.55 for the street had them in a few and they worked well in all street conditions...3.73 for me if those are the only choices...

    If wringing it out for everything it has is important on a somewhat reg basis, go 410. If it's more of a polite but spirited cruiser, hit up a set of 355s. Balance between the two = 373s.

    I have 3.55 in my car and you are out of 1st gear very fast. Anything higher and 1st gear is next to useless.
    Nice cruising gear and offers lot of power.

    I'm still on the fence but leaning towards 4.10 just for the fudge factor... And it will motivate me to change the valvetrain and heads to spin it up past 5k... I have until Wednesday to decide lol

    To be honest the difference between 1st gear (410 on a Z vs 373 on a T5) is 3.3% and 1.8% in 5th... But near 10% in the 2-4 gears...

    3.55 is a all around better choice in a 5 sp fox car.
