I just checked mine and I have gu2 - 2.73

Time for some 3.73's after my trip to Atlanta!

That is correct

.

GU2 = 2.73
GU5 = 3.23
GU6 = 3.42 (M6's only)

yea..1-2 around 56 or so mph...and 2-3 around 95..those would be the 2.73's....I dont know..im kinda liking my 2.73's..i guess there just growing on me..I mean, my car still seems fast even with those tall gears..and i can get pretty good gas mileage on the highway..
