Auto or 6Sp transmission?
The 2011 6Sp is new. It has different gear ratios compared to us with the 5sp. I have 3.73s in my 07 and prefer the ratio to 3.55 and 4.10 (both of which I've had). But you need advice form other guys with the same tranny as you, most of the guys who posted above have the 5spd.

IMO, you'd be happy with the 3:73s.

Some people will say it is the quality of the install but I know for a fact that they are more prone to it.
Some people do not run into problems with the Motives but the statistics don't lie.
Do research and you will find for yourself that the Motives are prone to causing problems.
Forums, shops, people....you'll find the Motive gears just aren't as good quality.
The motive gears are also NOT built as strong as the Ford Racing gears.

The Motives have a tendency to cause gear whine.

About this 3.31 vs 3.73 stuff...
Let me get this straight, 3.31:1 is 3.31 crank turns to one wheel turn. So by changing the axle ratio to 3.73:1 - or 3.73 crank turns to one wheel turn - I'm effectively putting more power into the rotation of the wheel. Does this show up on a dyno? It sounds like the power to the floor is increased.
One more question - I'm sold on the 3.73 because I want to use Ford Racing parts only - but if I buy it, is this something I can install myself? I have a moderate level of car knowledge and know how to crank a wrench...
Thanks - I hope this is still considered on subject.
Let me get this straight, 3.31:1 is 3.31 crank turns to one wheel turn. So by changing the axle ratio to 3.73:1 - or 3.73 crank turns to one wheel turn - I'm effectively putting more power into the rotation of the wheel. Does this show up on a dyno? It sounds like the power to the floor is increased.

What he said. That would be the best way of figuring out what you really wanted.
