Gear Ratio Spreadsheet
I wrote this a couple years ago, and just realized I never gave it a dedicated thread so people could find it.
This is a free-to-you Excel Spreadsheet available for download.
It will help you determine what rear gear ratio you would like, with what transmission gearing.
It will do the Math:
You enter your diff gear, tire size and transmission gearing
It will let you look at overall gear ratios, 1st gear ratio, top gear ratio, speed in every gear vs rpm, shift point rpm drops, cruise rpm, etc.
You can compare 4 speed, vs 5 speed vs 6 speed, etc.
