I was wondering what you guys think between the 2 gear ratio's.
Here in Canada our GT's come with 3.55's so I'm not sure if it would be worth the $500 to move up to 3.73. I would definitely pay for the upgrade in the US models but here I'm still debating it.

it is so worth it i have the 3.73s and love them or you could wait and go with 4.10s

DOOOO EEEEET! Sure, the 3.55s will suit you fine for a while.. but in a few months you will go "damn, I wish I'd gotten the 3.73s!"

The 2010 has a 3.38 low trans. The 2011 has a 3.66.

That means with the 2011 w/ 3.55 you will have a launch ratio like a 2010 with 3.84.
A 3.73 will be equivalent to 4.04.

If you ever go to to the Drag Strip you will run out of 4th gear before the finish line with 3.73 unless your at altitude.

Besides the lower 1st the new car will also have 22% more torque to deal with on street tires.

Believe it or not I ordered 3.31 (Base US Gears) in my car. Equivalent to 3.58 in the 2010.
I thought 3.73 was perfect in the stock 2010 but that was without the extra torque and speed to deal with.

Once I saw the ratios for the new trans, I ordered mine with the 3.55's.

Didn't make a big difference when MT ran a 12.8 1/4 mile in the 3.73 car

I'm kinda leaning for the 3.55's if you get the stock 235/50-18" tires and the 3.73's for the 245/(40 or 45)-19" tire/wheel options. With the HP/torque of the new motor, I think it might be a bit much to hook-up the 18" 's with the 3.73's.

I will be ordering the Brembo's so 19's it will be. If im not mistaken the width is 255 for the Brembo's.

Not sure if you can compare experiences between the 2010 and 2011.. 100 horses and a six speed may make a big difference in how tall you want your gears as far as drivability.

Yup. 255/40/19. Dems some big tires.
