I have 3:31 right now, and a chance to go to 3:55 for a great deal. What will be the difference?

 

From what I was told you wouldn't feel a big difference because that's a small change you're better off with 3.73 or 4.10 if you really want.

I'm going with 3.73, mainly because it's a DD car for me, going to order them soon after I get my exhaust installed.

 

Mine came with 3:55s and I love them....

 

Its not worth the money. Either do at least 3.73 or don't do it at all.

 

+1 3.33 to 3.55 won't feel too much different. A little but not much.

Of course, a lot depends on how you're driving your car. Even if you do a good bit of highway, 3.73's won't hurt you much over the 3.55's but WILL feel a lot better than the 3.33's. IMO there's little bang-for-the-buck going from 3.33's to 3.55's.

 

I have 3.55's in my Shelby GT and I think it gives the car a little quicker reaction.
But the Bullitt I drove that had the 3.73 seemed even more responsive.

If you're going to go through the expense you might as well get the 3.73

 

DONT FEAR THE GEAR !! Go with 4:10's and be done ! LOL

 

3.31 to 3.55 is a VERY noticeable difference. However, I have to agree with everyone else, if you're going to pay to have them installed, you might as well spring for at least 3.73s.

 

The major cost of a gear swap is labor. Don't be penny wise and pound foolish just because the parts are cheap. Get the gear you want, not the gear that's cheap! I have 4:10's in my daily driver and wish I had 3:73's but they came with the car when I bought it. I'd go 3:73.

 

Yeah, I was kinda yhinking 3:73, don't want 4:10 (did I just say that?) it's a daily driver with 41k on it (damn they went quick). I think 4:10's would be too much. I may hold out for the 3:73.
