3.73 or 3.55?
Just curious. I have my '10 GT on order, I opted for the 3.73 gears...and that's fine with me, but I'm wondering if perhaps I should have gone with the 3.55's?
Basically, im wondering, how do the 3.73's manage highway cruising speeds? Are your RPM's through the roof and is the engine racing all the time, or is it more normal than that?

The 3.73s will work just fine. I run 70 - 80 on the highway every day to work and my RPMs are in the low 2K range. If your worried about mpg, I get about 25 to 26mpg on the highway and 22 to 23 mpg going to and from work. But there are very few street lights where I am in Alabama. Get the 3.73 and have fun.

Be happy you went with the 3.73's, especially if you plan on getting different wheels/tires in the future that could possibly be a taller tire for the rear.
I have 295/45/18's out back, and with the overall extra height over stock, my gearing is equivalent to 3.3x gears, even though I have 3.55's. I don't know the exact math involved in figuring that out nor do I feel like it, but I read that if I had 3.73's, my gearing would be close to ~3.55's (which I have now). 3.90's would = ~3.73. 4.10's = ~3.90. You get the picture.
