Default 3.73s or 3.90s?

well i dont know what to do once again. i know i dont want 4.10s becasue this is my daily driver and 3.73s seem like im not doing enough...but i havent heard much on 3.90s other that they make some sort of noise? are they worth the money? idk if i trust buying Motive brand either i wanted FRPP but i dont see any 3.90s made by them.

Go with 4:10. There's little difference between 3:90 and 4:10 and there's little differnce between 3:73 and 3:90. There's a significant enough swing between 3:73 and 4:10 that it makes a huge difference in the feel of the car and it's fine on the highway. You will not regret it. I run 4:10 and mine is essentially my DD (unless it snows)

Get 4.10's I have them on my daily driver, I had 3.73's and were'nt satisfied with them. If you do decide to go 3.73's I have a set that I will sell you.

I would do gears next, but my driving habits contain ONLY highway driving, maybe 2 miles non highway a week. So if anything I would be going lower

eep, I am furthering my education in the city (providence RI) so I never even see my car unless I am leaving town, which is usually once a week to see the g/f who lives 50ish miles away

Go with the 4:10's!!!!!!!!!!!!!

They are not that bad on a DD.I had them for over a year on my GT and had 3:73's before (waste of money) and the 4:10's were a better gear.

Don't fear the gear!!

I have 3.90s in mine. Im glad I went with them over any other gear. 3.73s are a waste, get 3.90s or 4.10s. 3.90s SPECIFICALLY dont whine. If gears whine, you or your installer sucks.

round trip to work in the summer when i drive my car:
22 miles

i drive pretty fast around the city too.

my gas mileage with 4.10's is around 200-230
depending on if i have a really heavy foot that week.

trust me, i had 3.90, went to 4.10, and love them. i did notice a difference.

Your top speed is way more than 140mph. It is just that the computer will not let you go any faster. With 4.10's you will top out 4th gear at about 112mph. 5th could pull till 180mph.

Just do 4.10's. There has got to be a reason why everyone recommends them.

Put in 4.10's, remove the limiter, and let me know when you pull to 180mph.

theoretically 180 miles per hour is possible but the real world we live in has obstructions like friction and resistance. i would also like to see you pass even 160 in a stock gt, with no limiter on. lol

Exactly what I was getting at. Maybe in a perfect world you could. These mustangs are FAR from aerodynamic too. But, even in a perfect world you wouldnt be able to rev high enough to in 5th to reach 180mph.
