RPO Question
In checking the codes on my son's 2004 vert I find G90-3.15 ratio, then G92 rear axle performance. This makes me wonder what is the standard ratio for the 2004 with the 4L60E?

Nice to have the 3.15s on the car.

in reality... G92 = "optional ratio" but doesn't necessarily tell you what that optional ratio actually is.
And the G90 says what that optional ratio actually is (and for the C5 A4, it was the 3.15).
G90=3.15
Makes one wonder if originally more ratios were to be offered; thus the reason for the RPO codes being split up like that..

You have all that right there Tim, one note, G92 is a GM code, not specifuically a Corvette code, so you can find that in a Yukon, Malibu, Camaro, CTS, etc etc designating as you say "This car is equipped with an optional performance axle ratio"
Code:
