Gear Ratio/Speed Calculator

I spent a rainy Saturday morning making a spreadsheet that would tell me what speeds different RPMs, transmission gears, rear end gears and tire sizes would give me. Then later I found somebody did all the work for me.

It's aimed at 4-wheel-drives but you can ignore the transfer case stuff and it'll still work. It's great for dreaming about drivetrain possibilities.
