Can't wait to push them once broken in tho see the real difference. Then I will know for sure- but I can already state there is no problem with 4.56 on a daily driver...

So my gears are now broken in... and I have begun pushing them!
This is a nice improvement - the 4.56 gears are not radical by any means and are absolutely fine for a daily driver and freeway use. I like the ability to break loose off the line if desired (which I lost with my sticky tires), and there is definitely an improvement in acceleration.
As stated previously there is no gear whine/noise with the OEM part.
So, would I do it again? Perhaps...
This is not a cheap upgrade - I have about $1K all in (I opted to buy a entire 3rd member from a crashed FRS with 24K miles for $250, the gears were about $500, seals and gear setup ran $300).
The effects are noticeable but not drastic - I do wonder if I might have been happier with 4.88s - (I have a manual transmission - no question for an automatic). Of course gear noise and freeway driving might have been too much for me. I have a nagging doubt about not choosing 4.88; however I will never know...
Final conclusion: nice upgrade, a bit costly (though could have been cheaper with non-oem gears and no spare third member), total stealth mod and no California smog issues or dealer concerns, perhaps too conservative but still fun.
