Been looking around for some answers for a friend that has a new Stingray....he had some questions about the gear ratio's between the Z51's and the Standard Base models. I found a lot of info after digging into a lot of old threads here.....but they were all dealing with the 2014's.....and come to find out Chevy made a lot of little changes for 2015. I found a nice spec chart on Chevy's site and thought it would fit in nicely here.

This will help out some others the headache of digging around in really old threads.
