I have a h/c/i+100 shot C6 Z06 and just recently bought a stage 3 RPM C6Z diff which of course has 3.42 gears. As we all know there is no after market gears available for this diff. I know people have been talking about using the z51 trans ratio, but I was wondering what would be the absolute closest trans ratios 1st through 4th to make it like you had 3.90 gears out back? Im not sure what calculator to use to figure this out.

Really good ratio calculator I found in an old thread:
