TOOL: Graphical Transmission Gear Ratio Calculator
Neat online tool if you are looking to change your Wheel Size or Differential.
Plug in your current spec on the left, and proposed spec on the right, hit Calculate/Graph button and display the theoretical maximum MPH in each gear and impact on top end speed of changing the Wheels and/or Differential Gear Ratio.
I confirmed my upgrade of roughly 12% gain by going from a stock 2.81 differential to a 3.15 differential. My theoretical top end speed dropped from 208 to 185.
