4.10's installed!
I just had my 4.10's installed a week ago. After torturing myself through a few hundred break in miles all I can say is, "wow, why didn't I do this earlier?"
I have spent 3 years reading post after post and being torn between 4.10's and 3.73's. I was so afraid that my car would be useless on the freeway. To my pleasant suprise my rpm has barely increased on the freeway. What's really nice now is the ability to pass and still keep it in 5th gear.
To anyone torn, 4.10's are not as bad and you may think. Our 5th gear really makes up for it and the car is a beast from a stand still. It's launches like a rubber band now.

I am in the same boat, I went to a local shop two days ago to get a price, and they warned me against the 4.10's. They said it would be way too much gear, but I kinda think I would like them. My 08 GT is not a daily driver, more like a weekend, nice day driver. I rarely take it out on the highway anyways. What did it cost ya, and did you order the bearings (install kit) with it?

Seeing that you have a manual, then go with 4.10s. I drive about 250 highway miles per. week and I have no problems with the 4.10s. Even at the track with street tires I have cut sub 2s on a few occasions.

I only replaced the pinion bearing. My car has just over 12,000 miles so everything looked good. Install only cost $200.
I went with the 4.10's after three years of reading, thinking, reading, thinking. Finally decided I would rather get a gear that is too much and decide to go back (to 3.55 or 3.73) than have 3.73 installed and not be happy.
I can't praise the 4.10's enough. Like I said intially, my freeway rpm is perfectly fine to me. Only went up a couple hundred. It's not like I'm near redline now when on the freeway. I think it went up around 200rpm in 5th gear. It was so little I only noticed the very first time I drove it. Since then I haven't noticed it once.
