Stock Gear Ratio GT Premium

hey forum, I was just wondering what the stock rear end ratio was for gt premium. I know if you get the track package, you get 3.73, but what about for the regular brembo break package? thanks

Not positive but could be a 3.31 or 3.55. If you check on the diff. of the car you should see a sticker that tells you which ratio it is.

If it's unlisted it will be 3.31

My brembo has 3.31 per the tag on the chunk and my sticker.

I seen a new one the other day with a 3.05 in it :| ... Think it was a 3.05

The standard gears for 2011-2013 GT Manuals is 3.31.
3.55 and 3.73's are optional.
The only cars that get 3.73's as standard is a `13 Track Pack and a Boss because that gear is part of the package.

I've been wondering...how come you can't get 3.55s and 3.73s in a convertible?

My '08 has factory 3.55s thankfully, but you can't get them from the factory anymore. I wonder why that is?
