I have the 2011 v6 Mustang and I understand that the gears are 2.73s. I belive the GT cars have 3.31 gears. Well I've always been kind of a hotrodder so I like that acceleration. Don't want to spend a lot of money cause the car is leased. Have thought about a tuner but I belive that a change to 3.31s would be the most bang for the buck. What do ya think guys any opinions?

I would probably do 355s or 373s if you really want acceleration. I rode in a manual 2011 last night and I'm pretty sure his 1st gear redlined around 50mph...

 

Why I was interested in 3.31s is, I believe what was stock in the v6 last year. I also want to be able to drive this car on an interstate once in a while, so are the 3.55s or the 3.73s going to be two much for me. Thanks!

In the auto Rpm`s at 75 MHP as calculated thru a system with the 2011 auto gear ratios in it.

2.73-1740, 3.31-2150, 3.55-2265, 3.73-2377, 4.10-2617.

That is with 235-50 18 inch tires. Data is approximate and revs will be a little higher for 17 inch wheels w/ -50 tires.

 

I have 3.31 in my v6, had 3.73 in my '10 GT both are fine for highway driving, if you want that lower end kick and still have a nice highway gear 3.73, but the 3.31's work great for me down low and better on highway than 3.73, if thinking of a 4.10..... would not be good for highway, but down low would be boss.

 

I'm at 2,000 @ 72 mph

 

Finally got the 3.55 gears in, the car doesn't feel much better above 50 MPH but is much better at low speed.

 

Why would you expect anything different?

 

hmmm 2,000rpms @ 72mph

guess the guy at the dealer told me a lie

he told me my car had 3.31's and my car is a 2,000rpms @ 80mph

guess I'm going to have to get some gears

 

You check the sticker on the differential?
